1. Refractive displacement of the radio-emission footprint of inclined air showers simulated with CoREAS

Author: Felix Schlüter, Marvin Gottowik, Tim Huege, and Julian Rautenberg
Subjects: Astrophysics, QB460-466, Nuclear and particle physics. Atomic energy. Radioactivity, QC770-798
Abstract: Abstract The footprint of radio emission from extensive air showers is known to exhibit asymmetries due to the superposition of geomagnetic and charge-excess radiation. For inclined air showers a geometric early-late effect disturbs the signal distribution further. Correcting CoREAS simulations for these asymmetries reveals an additional disturbance in the signal distribution of highly inclined showers in atmospheres with a realistic refractive index profile. This additional apparent asymmetry in fact arises from a systematic displacement of the radio-emission footprint with respect to the Monte-Carlo shower impact point on the ground. We find a displacement of $$\sim 1500$$ ∼1500 m in the ground plane for showers with a zenith angle of $$85^{\circ }$$ 85∘ , illustrating that the effect is relevant in practical applications. A model describing this displacement by refraction in the atmosphere based on Snell’s law yields good agreement with our observations from CoREAS simulations. We thus conclude that the displacement is caused by refraction in the atmosphere.

Abstract: Small and medium-sized enterprises (SMEs) often lack the knowledge and the resources necessary to implement best ractices in environmental management. This makes them a relevant target for public policy measures trying to enhance sustainable decision making in the economy. This paper reports the results of a field experiment in Switzerland investigating behavioral economic interventions for promoting an environmental consulting program to SMEs. The experiment tested the effectiveness of appealing to the environmental vs. financial benefits of environmental consulting to promote the program to SMEs, and of loss vs. gain framed nudges. The results indicate that loss frames are not more effective than gain frames. Unlike suggested by previous approaches, appealing to the environmental benefits of sustainability measures is just as effective as underlining the financial benefits for the SMEs. Evidence from two surveys with SME decision makers corroborates this latter result: SMEs indicate that personal motivations of owners or managers and long-term environmental impact - rather than potential financial benefits - are the most important factors determining whether they are willing to implement additional environmental sustainability measures.

3. Reconstructing inclined extensive air showers from radio measurements

Author: Felix Schlüter and Tim Huege
Subjects: High Energy Astrophysical Phenomena (astro-ph.HE), Physics, FOS: Physical sciences, ddc:530, Astrophysics - Instrumentation and Methods for Astrophysics, Astrophysics - High Energy Astrophysical Phenomena, Instrumentation and Methods for Astrophysics (astro-ph.IM)
Abstract: We present a reconstruction algorithm for extensive air showers with zenith angles between 65$^\circ$ and 85$^\circ$ measured with radio antennas in the 30-80 MHz band. Our algorithm is based on a signal model derived from CoREAS simulations which explicitly takes into account the asymmetries introduced by the superposition of charge-excess and geomagnetic radiation as well as by early-late effects. We exploit correlations among fit parameters to reduce the dimensionality and thus ensure stability of the fit procedure. Our approach reaches a reconstruction efficiency near 100% with an intrinsic resolution for the reconstruction of the electromagnetic energy of well below 5\%. It can be employed in upcoming large-scale radio detection arrays using the 30-80 MHz band, in particular the AugerPrime Radio detector of the Pierre Auger Observatory, and can likely be adapted to experiments such as GRAND operating at higher frequencies., Proceedings of the ICRC2021 conference

Abstract: Simulating the radio emission of inclined extensive air showers for a ground-based radio-antenna array we find a systematic displacement of the radio emission with respect to the Monte-Carlo shower impact point. We correct the radio-emission footprint for the asymmetries due to the superposition of geomagnetic and charge-excess radiation as well as for the early-late effect. The remaining displacement is found to be ∼1500 m along the ground plane for showers with a zenith angle of 85°, which is relevant for air shower detectors. A model describing this displacement by refraction in the atmosphere based on Snell’s law yields good agreement with our observations from CoREAS simulations. We thus conclude that the displacement is caused by refraction in the atmosphere.

Abstract: The Pierre Auger Observatory, at present the largest cosmic-ray observatory ever built, is instrumented with a ground array of 1600 water-Cherenkov detectors, known as the Surface Detector (SD). The SD samples the secondary particle content (mostly photons, electrons, positrons and muons) of extensive air showers initiated by cosmic rays with energies ranging from $10^{17}~$eV up to more than $10^{20}~$eV. Measuring the independent contribution of the muon component to the total registered signal is crucial to enhance the capability of the Observatory to estimate the mass of the cosmic rays on an event-by-event basis. However, with the current design of the SD, it is difficult to straightforwardly separate the contributions of muons to the SD time traces from those of photons, electrons and positrons. In this paper, we present a method aimed at extracting the muon component of the time traces registered with each individual detector of the SD using Recurrent Neural Networks. We derive the performances of the method by training the neural network on simulations, in which the muon and the electromagnetic components of the traces are known. We conclude this work showing the performance of this method on experimental data of the Pierre Auger Observatory. We find that our predictions agree with the parameterizations obtained by the AGASA collaboration to describe the lateral distributions of the electromagnetic and muonic components of extensive air showers., Comment: Published version, 23 pages, 15 figures

Abstract: FRAM (F/Photometric Robotic Atmospheric Monitor) is a robotic telescope operated at the Pierre Auger Observatory in Argentina for the purposes of atmospheric monitoring using stellar photometry. As a passive system which does not produce any light that could interfere with the observations of the fluorescence telescopes of the observatory, it complements the active monitoring systems that use lasers. We discuss the applications of stellar photometry for atmospheric monitoring at optical observatories in general and the particular modes of operation employed by the Auger FRAM. We describe in detail the technical aspects of FRAM, the hardware and software requirements for a successful operation of a robotic telescope for such a purpose and their implementation within the FRAM system., Published version, 27 pages, 8 figures

Abstract: Interferometric measurements with arrays of radio antennas are a powerful and widely used technique in astronomy. Recently, this technique has been revisited for the reconstruction of extensive air showers [1]. This radio-interferometric technique exploits the coherence in the radio emission emitted by billions of secondary shower particles to reconstruct the shower parameters, in particular the shower axis and depth of the shower maximum $X_\mathrm{max}$. The accuracy previously demonstrated on simulations with an idealized detector is very promising. In this article we evaluate the potential of interferometric $X_\mathrm{max}$ measurements using (simulated) inclined air showers with sparse antenna arrays under realistic conditions. To determine prerequisites for the application of the radio-interferometric technique with various antenna arrays, the influence of inaccuracies in the time synchronisation between antennas and its inter-dependency with the antenna density is investigated in detail. We find a strong correlation between the antenna multiplicity (per event) and the maximum acceptable time jitter, i.e., inaccuracy in the time synchronisation. For data recorded with a time synchronisation accurate to within 1 ns in the commonly used frequency band of 30 to 80 MHz, an antenna multiplicity of $> 50$ is needed to achieve an $X_\mathrm{max}$ resolution of $\sigma_{X_\mathrm{max}} \lesssim 20$ g cm$^{-2}$. For data recorded with 2 ns accuracy, already $\gtrsim 200$ antennas are needed to achieve this $X_\mathrm{max}$ resolution. Furthermore, we find no advantage reconstructing $X_\mathrm{max}$ from data simulated at higher observation frequencies, i.e., up to several hundred MHz. Finally, we provide a generalisation of our results from very inclined air showers to vertical geometries.

We find that the measured fluctuations are in good agreement with predictions from air shower simulations. This observation provides new insights into the origin of the previously reported deficit of muons in air shower simulations and constrains models of hadronic interactions at ultrahigh energies. Our measurement is compatible with the muon deficit originating from small deviations in the predictions from hadronic interaction models of particle production that accumulate as the showers develop., Argentina-Comision Nacional de Energia Atomica, ANPCyT, Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET), Gobierno de la Provincia de Mendoza, Municipalidad de Malargue, NDM Holdings, Valle Las Lenas, Australian Research Council, Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ), Fundacao de Apoio a Pesquisa do Distrito Federal (FAPDF), Financiadora de Inovacao e Pesquisa (Finep), Fundacao Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio De Janeiro (FAPERJ), Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP) 2019/10151-2 2010/07359-6 1999/05404-3, Ministerio da Ciencia, Tecnologia, Inovacoes e Comunicacoes (MCTIC), Ministry of Education, Youth & Sports - Czech Republic MSMT CR LTT18004 LM2015038 LM2018102 CZ.02.1.01/0.0/0.0/16_013/0001402 CZ.02.1.01/0.0/0.0/18_046/0016010 CZ.02.1.01/0.0/0.0/17_049/0008422, France-Centre de Calcul IN2P3/CNRS, Centre National de la Recherche Scientifique (CNRS), Region Ile-de-France, Departement Sciences de l'Univers (SDU-INSU/CNRS), French National Research Agency (ANR) LABEX ANR-10-LABX-63 ANR11-IDEX-0004-02, Federal Ministry of Education & Research (BMBF), German Research Foundation (DFG), Finanzministerium Baden-Wurttemberg, Helmholtz Alliance for Astroparticle Physics (HAP), Helmholtz Association, Ministerium fur Innovation, Wissenschaft und Forschung des Landes Nordrhein-Westfalen, Ministerium fur Wissenschaft, Forschung und Kunst des Landes Baden-Wurttemberg, Italy-Istituto Nazionale di Fisica Nucleare (INFN), Istituto Nazionale Astrofisica (INAF), Ministry of Education, Universities and Research (MIUR), CETEMPS Center of Excellence, Ministry of Foreign Affairs and International Cooperation (Italy), Consejo Nacional de Ciencia y Tecnologia (CONACyT) 167733, Universidad Nacional Autonoma de Mexico (UNAM), PAPIIT DGAPA-UNAM, Netherlands-Ministry of Education, Culture and Science, Netherlands Organization for Scientific Research (NWO), Dutch national e-infrastructure, SURF Cooperative, Poland-Ministry of Science and Higher Education DIR/WK/2018/11, National Science Centre, Poland 2013/08/M/ST9/00322 2016/23/B/ST9/01635 HARMONIA 5-2013/10/M/ST9/00062 UMO-2016/22/M/ST9/00198, Portugal -Portuguese national funds, FEDER funds within Programa Operacional Factores de Competitividade through Fundacao para a Ciencia e a Tecnologia (COMPETE), Romania-Romanian Ministry of Education and Research, the Program Nucleu within MCI PN19150201/16N/2019 PN19060102, Romania-Romanian Ministry of Educatio n and Research, the Program Nucleu within PNCDI III PN-III-P1-1.2-PCCDI-2017-0839/19PCCDI/2018, Slovenian Research Agency - Slovenia P1-0031 P1-0385 I00033 N1-0111, Spain-Ministerio de Economia, Industria y Competitividad FPA2017-85114-P FPA2017-85197-P, Xunta de Galicia European Commission ED431C 2017/07, Junta de Andalucia SOMM17/6104/UGR, European Commission, RENATA Red Nacional Tematica de Astroparticulas FPA2015-68783-REDT, Maria de Maeztu Unit of Excellence MDM-2016-0692, United States Department of Energy (DOE) DE-AC0207CH11359 DE-FR02-04ER41300 DE-FG0299ER41107 DE-SC0011689, National Science Foundation (NSF) 0450696, Grainger Foundation, Marie Curie-IRSES/EPLANET, European Particle Physics Latin American Network, UNESCO

It consists of an array of 61 water Cherenkov detectors on a denser spacing in combination with underground scintillation detectors used for muon density measurement. Each detector is composed of three scintillation modules, with 10 m(2) detection area per module, buried at 2.3 m depth, resulting in a total detection area of 30 m(2). Silicon photomultiplier sensors (SiPM) measure the amount of scintillation light generated by charged particles traversing the modules. In this paper, the design of the front-end electronics to process the signals of those SiPMs and test results from the laboratory and from the Pierre Auger Observatory are described. Compared to our previous prototype, the new electronics shows a higher performance, higher efficiency and lower power consumption, and it has a new acquisition system with increased dynamic range that allows measurements closer to the shower core. The new acquisition system is based on the measurement of the total charge signal that the muonic component of the cosmic ray shower generates in the detector., Argentina - Comision Nacional de Energia Atomica, Argentina - Agencia Nacional de Promocion Cientifica y Tecnologica (ANPCyT), Argentina - Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET), Argentina - Gobierno de la Provincia de Mendoza, Argentina - Municipalidad de Malargue, Argentina - NDM Holdings, Argentina - Valle Las Lenas, Australian Research Council, Conselho Nacional de Desenvolvimento Cientifico e Tecnologico (CNPQ) Fundacao de Apoio a Pesquisa do Distrito Federal (FAPDF) Brazil - Financiadora de Estudos e Projetos (FINEP), Fundacao Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio De Janeiro (FAPERJ), Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP) 2019/10151-2 2010/07359-6 1999/05404-3, Brazil - Ministerio da Ciencia, Tecnologia, Inovacoes e Comunicacoes (MCTIC), Brazil - Czech Republic Grant MSMT CR LTT18004 LM2015038 LM2018102 CZ.02.1.01/0.0/0.0/16_013/0001402 CZ.02.1.01/0.0/0.0/18_046/0016010 CZ.02.1.01/0.0/0.0/17_049/0008422, France - Centre de Calcul IN2P3/CNRS, Centre National de la Recherche Scientifique (CNRS), France - Conseil Regional Ile-de-France, France - Departement Physique Nucleaire et Corpusculaire (PNC-IN2P3/CNRS), France - Departement Sciences de l'Univers (SDU-INSU/CNRS), French National Research Agency (ANR) LABEX ANR-10-LABX-63, Institut Lagrange de Paris (ILP) within the Investissements d'Avenir Programme ANR-11-IDEX-0004-02, Federal Ministry of Education & Research (BMBF), Bundesministerium fur Bildung und Forschung (BMBF), German Research Foundation (DFG), Germany - Finanzministerium Baden-Wurttemberg, Germany - Helmholtz Alliance for Astroparticle Physics (HAP), Germany - Helmholtz-Gemeinschaft Deutscher Forschungszentren (HGF), Germany - Ministerium fur Innovation, Wissenschaft und Forschung des Landes Nordrhein-Westfalen, Germany - Ministerium fur Wissenschaft, Forschung und Kunst des Landes Baden-Wurttemberg, Italy - Istituto Nazionale di Fisica Nucleare (INFN), Italy - Istituto Nazionale di Astrofisica (INAF), Italy - Ministero dell'Istruzione, dell'Universita e della Ricerca (MIUR), Italy - CETEMPS Center of Excellence, Consejo Nacional de Ciencia y Tecnologia (CONACyT) 167733, Mexico - Universidad Nacional Autonoma de Mexico (UNAM), Mexico - PAPIIT DGAPA-UNAM, Netherlands - Ministry of Education, Culture and Science, Netherlands Organization for Scientific Research (NWO), Netherlands Organisation for Scientific Research (NWO), The Netherlands - SURF Cooperative, Poland - Ministry of Science and Higher Education DIR/WK/2018/11 Poland - National Science Centre 2013/08/M/ST9/00322 2016/23/B/ST9/01635 HARMONIA 5-2013/10/M/ST9/00062 UMO-2016/22/M/ST9/00198, Portugal - Portuguese national funds Portugal - FEDER funds within Programa Operacional Factores de Competitividade through Fundacao para a Ciencia e a Tecnologia (COMPETE), Romania - Romanian Ministry of Education and Research Romania - Program Nucleu within MCI PN19150201/16N/2019 PN19060102 Romania - PNCDI III PN-III-P1-1.2-PCCDI-2017-0839/19PCCDI/2018, Slovenian Research Agency - Slovenia P1-0031 P1-0385 I0-0033 N1-0111, Spain - Ministerio de Economia, Industria y Competitividad FPA2017-85114-P FPA2017-85197-P, Spain - Xunta de Galicia ED431C 2017/07, Junta de Andalucia SOMM17/6104/UGR, Spain - Feder Funds, Spain - RENATA Red Nacional Tematica de Astroparticulas FPA2015-68783-REDT, Spain - Maria de Maeztu Unit of Excellence MDM-2016-0692, United States Department of Energy (DOE) DE-AC02-07CH11359, National Science Foundation (NSF) 0450696, U.S.A. - Grainger Foundation U.S.A. - Marie Curie-IRSES/EPLANET U.S.A. - European Particle Physics Latin American Network U.S.A. - UNESCO, Italy - Ministero degli Affari Esteri (MAE), The Netherlands - Dutch national e-infrastructure

Abstract: The atmospheric depth of the air shower maximum $X_{\mathrm{max}}$ is an observable commonly used for the determination of the nuclear mass composition of ultra-high energy cosmic rays. Direct measurements of $X_{\mathrm{max}}$ are performed using observations of the longitudinal shower development with fluorescence telescopes. At the same time, several methods have been proposed for an indirect estimation of $X_{\mathrm{max}}$ from the characteristics of the shower particles registered with surface detector arrays. In this paper, we present a deep neural network (DNN) for the estimation of $X_{\mathrm{max}}$. The reconstruction relies on the signals induced by shower particles in the ground based water-Cherenkov detectors of the Pierre Auger Observatory. The network architecture features recurrent long short-term memory layers to process the temporal structure of signals and hexagonal convolutions to exploit the symmetry of the surface detector array. We evaluate the performance of the network using air showers simulated with three different hadronic interaction models. Thereafter, we account for long-term detector effects and calibrate the reconstructed $X_{\mathrm{max}}$ using fluorescence measurements. Finally, we show that the event-by-event resolution in the reconstruction of the shower maximum improves with increasing shower energy and reaches less than $25~\mathrm{g/cm^{2}}$ at energies above $2\times 10^{19}~\mathrm{eV}$., Published version, 29 pages, 12 figures

An inflection of the spectrum is observed, confirming the presence of the so-called second-knee feature. The spectrum is then combined with that of the 1500 m array to produce a single measurement of the flux, linking this spectral feature with the three additional breaks at the highest energies. The combined spectrum, with an energy scale set calorimetrically via fluorescence telescopes and using a single detector type, results in the most statistically and systematically precise measurement of spectral breaks yet obtained. These measurements are critical for furthering our understanding of the highest energy cosmic rays., ANR-10-LABX-63 ANR-11-IDEX-0004-02, Belgium – Fonds de la Recherche Scientifique, Comisión Nacional de Energía Atómica, Département Physique Nucléaire et Corpusculaire PNC-IN2P3/CNRS, Département Sciences de l’Univers, Feder Funds, María de Maeztu Unit of Excellence MDM-2016-0692, Ministero degli Affari Esteri, RENATA Red Nacional Temática de Astropartículas FPA2015-68783-REDT, SURF, National Science Foundation 0450696, U.S. Department of Energy DE-AC02-07CH11359, DE-FG02-99ER41107, DE-FR02-04ER41300, DE-SC0011689, University of Delaware Research Foundation, United Nations Educational, Scientific and Cultural Organization, Australian Research Council, Helmholtz-Gemeinschaft, Deutsche Forschungsgemeinschaft, Fundação de Amparo à Pesquisa do Estado de São Paulo 1999/05404-3, 2010/07359-6, 2019/10151-2, Fundação para a Ciência e a Tecnologia, Bundesministerium für Bildung und Forschung, Fonds De La Recherche Scientifique - FNRS, Consejo Nacional de Investigaciones Científicas y Técnicas, Agencia Nacional de Promoción Científica y Tecnológica, Fonds Wetenschappelijk Onderzoek, Consejo Nacional de Ciencia y Tecnología 167733, Ministerie van Onderwijs, Cultuur en Wetenschap, Nederlandse Organisatie voor Wetenschappelijk Onderzoek, Ministero dell’Istruzione, dell’Università e della Ricerca, Ministerium für Wissenschaft, Forschung und Kunst Baden-Württemberg, Conselho Nacional de Desenvolvimento Científico e Tecnológico, Conseil Régional, Île-de-France, Instituto Nazionale di Fisica Nucleare, Narodowe Centrum Nauki 2013/08/M/ST9/00322, 2013/10/M/ST9/00062, 2016/23/B/ST9/01635, UMO-2016/22/M/ST9/00198, Javna Agencija za Raziskovalno Dejavnost RS I0-0033, N1-0111, P1-0031, P1-0385, Ministerstwo Edukacji i Nauki DIR/WK/2018/11, Fundação Carlos Chagas Filho de Amparo à Pesquisa do Estado do Rio de Janeiro, Centre National de la Recherche Scientifique, Financiadora de Estudos e Projetos, Istituto Nazionale di Astrofisica, Universidad Nacional Autónoma de México, Ministry of Education and Research, Romania PN-III-P1-1.2-PCCDI-2017-0839/19PCCDI/2018, PN19060102, PN19150201/16N/2019, European Regional Development Fund, Ministerium für Innovation, Wissenschaft und Forschung des Landes Nordrhein-Westfalen, Ministerio de Economía, Industria y Competitividad, Gobierno de España FPA2017-85114-P, PID2019-104676GB-C32, Xunta de Galicia ED431C 2017/07, Junta de Andalucía P18-FR-4314, Ministério da Ciência, Tecnologia, Inovações e Comunicações CZ.02.1.01/0.0/0.0/16_013/0001402, CZ.02.1.01/0.0/0.0/17_049/0008422, CZ.02.1.01/0.0/0.0/18_046/0016010, LM2015038, LM2018102, MSMT CR LTT18004, Programa Operacional Temático Factores de Competitividade, Institut Lagrange de Paris

Abstract: The footprint of radio emission from extensive air showers is known to exhibit asymmetries due to the superposition of geomagnetic and charge-excess radiation. For inclined air showers a geometric early-late effect disturbs the signal distribution further. Correcting CoREAS simulations for these asymmetries reveals an additional disturbance in the signal distribution of highly inclined showers in atmospheres with a realistic refractive index profile. This additional apparent asymmetry in fact arises from a systematic displacement of the radio-emission footprint with respect to the Monte-Carlo shower impact point on the ground. We find a displacement of $$\sim 1500$$∼1500 m in the ground plane for showers with a zenith angle of $$85^{\circ }$$85∘, illustrating that the effect is relevant in practical applications. A model describing this displacement by refraction in the atmosphere based on Snell’s law yields good agreement with our observations from CoREAS simulations. We thus conclude that the displacement is caused by refraction in the atmosphere.

Abstract: Extensive air showers, originating from ultra-high energy cosmic rays, have been successfully measured through the use of arrays of water-Cherenkov detectors (WCDs). Sophisticated analyses exploiting WCD data have made it possible to demonstrate that shower simulations, based on different hadronic-interaction models, cannot reproduce the observed number of muons at the ground. The accurate knowledge of the WCD response to muons is paramount in establishing the exact level of this discrepancy. In this work, we report on a study of the response of a WCD of the Pierre Auger Observatory to atmospheric muons performed with a hodoscope made of resistive plate chambers (RPCs), enabling us to select and reconstruct nearly 600 thousand single muon trajectories with zenith angles ranging from 0º to 55º. Comparison of distributions of key observables between the hodoscope data and the predictions of dedicated simulations allows us to demonstrate the accuracy of the latter at a level of 2%. As the WCD calibration is based on its response to atmospheric muons, the hodoscope data are also exploited to show the long-term stability of the procedure., La lista completa de autores que integran el documento puede consultarse en el archivo., Facultad de Ciencias Exactas, Instituto de Física La Plata

Abstract: The time and location of the 1,598 verified and reconstructed elves, used for the analysis showcased in this paper, are publicly available on the website of the Pierre Auger Observatory (https://www.auger.org/ index.php/science/data). We wish to thank the World Wide Lightning Location Network (http://wwlln.net), a collaboration among over 50 universities and institutions, for providing the lightning location data used in this paper. We acknowledge Robert Marshall for providing one of the most advanced elve simulations to the public, a key tool in understanding the elves observed by the Pierre Auger Observatory. The successful installation, commissioning, and operation of the Pierre Auger Observatory would not have been possible without the strong commitment and effort from the technical and administrative staff in Malargüe., Elves are a class of transient luminous events, with a radial extent typically greater than 250 km, that occur in the lower ionosphere above strong electrical storms. We report the observation of 1,598 elves, from 2014 to 2016, recorded with unprecedented time resolution (100 ns) using the fluorescence detector (FD) of the Pierre Auger Cosmic-Ray Observatory. The Auger Observatory is located in the Mendoza province of Argentina with a viewing footprint for elve observations of 3 · 106 km2, reaching areas above the Pacific and Atlantic Oceans, as well as the Córdoba region, which is known for severe convective thunderstorms. Primarily designed for ultrahigh energy cosmic-ray observations, the Auger FD turns out to be very sensitive to the ultraviolet emission in elves. The detector features modified Schmidt optics with large apertures resulting in a field of view that spans the horizon, and year-round operation on dark nights with low moonlight background, when the local weather is favorable. The measured light profiles of 18% of the elve events have more than one peak, compatible with intracloud activity. Within the 3-year sample, 72% of the elves correlate with the far-field radiation measurements of the World Wide Lightning Location Network. The Auger Observatory plans to continue operations until at least 2025, including elve observations and analysis. To the best of our knowledge, this observatory is the only facility on Earth that measures elves with year-round operation and full horizon coverage., Argentina—Comisión Nacional de Energía Atómica; Agencia Nacional de Promoción Científica y Tecnológica (ANPCyT); Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET); Gobierno de la Provincia de Mendoza; Municipalidad de Malargüe; and NDM Holdings and Valle Las Leñas, in gratitude for their continuing cooperation over land access; Australia—the Australian Research Council; Brazil—Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Financiadora de Estudos e Projetos (FINEP); Fundação de Amparo à Pesquisa do Estado de Rio de Janeiro (FAPERJ); São Paulo Research Foundation (FAPESP) Grants 2010/07359-6 and 1999/05404-3; Ministério da Ciência, Tecnologia, Inovações e Comunicações (MCTIC); Czech Republic—Grants MSMT CRLTT18004, LO1305, LM2015038, and CZ.02.1.01/0.0/0.0/16_013/0001402; France—Centre de Calcul IN2P3/CNRS; Centre National de la Recherche Scientifique (CNRS); Conseil Régional Ile-de-France; Département Physique Nucléaire et Corpusculaire (PNC-IN2P3/CNRS); Département Sciences de l'Univers (SDU-INSU/CNRS); Institut Lagrange de Paris (ILP) Grant LABEX ANR-10-LABX-63 within the Investissements d'Avenir Programme Grant ANR-11-IDEX-0004-02; Germany—Bundesministerium für Bildung und Forschung (BMBF); Deutsche Forschungsgemeinschaft (DFG); Finanzministerium Baden-Württemberg; Helmholtz Alliance for Astroparticle Physics (HAP); Helmholtz-Gemeinschaft.

Abstract: Cosmic rays arriving at Earth collide with the upper parts of the atmosphere, thereby inducing extensive air showers. When secondary particles from the cascade arrive at the ground, they are measured by surface detector arrays. We describe the methods applied to the measurements of the surface detector of the Pierre Auger Observatory to reconstruct events with zenith angles less than 60 using the timing and signal information recorded using the water-Cherenkov detector stations. In addition, we assess the accuracy of these methods in reconstructing the arrival directions of the primary cosmic ray particles and the sizes of the induced showers., Argentina - Comisión Nacional de Energía Atómica, Argentina - Agencia Nacional de Promoción Científica y Tecnológica (ANPCyT), Argentina - Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Argentina - Gobierno de la Provincia de Mendoza, Argentina - Municipalidad de Malargue, Argentina - NDM Holdings, Argentina - Valle Las Lenas, Australia - Australian Research Council, National Council for Scientific and Technological Development (CNPq), Brazil - Financiadora de Estudos e Projetos (FINEP), Carlos Chagas Filho Foundation for Research Support of the State of Rio de Janeiro (FAPERJ), Fundacao de Amparo a Pesquisa do Estado de Sao Paulo (FAPESP) 2019/10151-2 2010/07359-6 1999/05404-3, Brazil - Ministerio da Ciencia, Tecnologia, Inovacoes e Comunicacoes (MCTIC), Czech Republic Grant MSMT CR LTT18004 LM2015038 LM2018102 CZ.02.1.01/0.0/0.0/16_013/0001402 CZ.02.1.01/0.0/0.0/18_046/0016010 CZ.02.1.01/0.0/0.0/17_049/0008422, France - Centre de Calcul IN2P3/CNRS, Centre National de la Recherche Scientifique (CNRS), France - Conseil Regional Ile-de-France, France - Departement Physique Nucleaire et Corpusculaire (PNC-IN2P3/CNRS), France - Departement Sciences de l'Univers (SDU-INSU/CNRS), French National Research Agency (ANR) LABEX ANR-10-LABX-63 ANR11-IDEX-0004-02, Federal Ministry of Education & Research (BMBF), German Research Foundation (DFG), Germany - Finanzministerium Baden-Wurttemberg, Germany - Helmholtz Alliance for Astroparticle Physics (HAP), Germany - Helmholtz-Gemeinschaft Deutscher Forschungszentren (HGF), Germany - Min-isterium fur Innovation, Wissenschaft und Forschung des Landes Nordrhein-Westfalen, Germany - Ministerium fur Wissenschaft, Forschung und Kunst des Landes Baden-Wurttemberg, Italy - Istituto Nazionale di Fisica Nucleare (INFN), Italy - Istituto Nazionale di Astrofisica (INAF), Italy - Ministero dell'Istruzione, dell'Universita e della Ricerca (MIUR), Italy - CETEMPS Center of Excellence, Italy - Ministero degli Affari Esteri (MAE), Consejo Nacional de Ciencia y Tecnología (CONACyT) 167733, México - Universidad Nacional Autónoma de México (UNAM), México - PAPIIT DGAPA-UNAM, The Netherlands - Ministry of Education, Culture and Science, Netherlands Organization for Scientific Research (NWO), The Netherlands - Dutch national e-infrastructure, The Netherlands - SURF Cooperative, Poland - Ministry of Science and Higher Education DIR/WK/2018/11, Poland - National Science Centre 2013/08/M/ST9/00322 2016/23/B/ST9/01635 HARMONIA 52013/10/M/ST9/00062 UMO-2016/22/M/ST9/00198, Portugal - Portuguese national funds, Portugal - FEDER funds within Programa Operacional Factores de Competitividade through Fundacao para a Ciencia e a Tecnologia (COMPETE), Romania - Romanian Ministry of Education and Research, the Program Nucleu within MCI PN19150201/16N/2019 PN19060102, Romania - Romanian Ministry of Education and Research, the Program Nucleu within PNCDI III PN-III-P11.2-PCCDI-2017-0839/19PCCDI/2018, Slovenian Research Agency - Slovenia P1-0031 P1-0385 I0-0033 N1-0111, Spain - Ministerio de Economía, Industria y Competitividad FPA2017-85114-P FPA2017-85197-P, Spain - Xunta de Galicia ED431C 2017/07, Junta de Andalucía SOMM17/6104/UGR, Spain - Feder Funds, Spain - RENATARedNacional Tematica de Astroparticulas FPA2015-68783-REDT, Spain - Maria de MaeztuUnit of Excellence MDM-2016-0692, United States Department of Energy (DOE) DE-AC02-07CH11359 DE-FR02-04ER41300 DEFG02-99ER41107 DE-SC0011689, National Science Foundation (NSF) 0450696, U.S.A. - Grainger Foundation, U.S.A. - Marie Curie-IRSES/EPLANET, U.S.A. - European Particle Physics Latin American Network, U.S.A. - UNESCO

Abstract: The hybrid design of the Pierre Auger Observatory allows for the measurement of the properties of extensive air showers initiated by ultra-high energy cosmic rays with unprecedented precision. By using an array of prototype underground muon detectors, we have performed the first direct measurement, by the Auger Collaboration, of the muon content of air showers between $$2\times 10^{17}$$2×1017 and $$2\times 10^{18}$$2×1018 eV. We have studied the energy evolution of the attenuation-corrected muon density, and compared it to predictions from air shower simulations. The observed densities are found to be larger than those predicted by models. We quantify this discrepancy by combining the measurements from the muon detector with those from the Auger fluorescence detector at $$10^{{17.5}}\, {\mathrm{eV}} $$1017.5eV and $$10^{{18}}\, {\mathrm{eV}} $$1018eV. We find that, for the models to explain the data, an increase in the muon density of $$38\%$$38%$$\pm 4\% (12\%)$$±4%(12%)$$\pm {}^{21\%}_{18\%}$$±18%21% for EPOS-LHC, and of $$50\% (53\%)$$50%(53%)$$\pm 4\% (13\%)$$±4%(13%)$$\pm {}^{23\%}_{20\%}$$±20%23% for QGSJetII-04, is respectively needed.

Abstract: Radio detection of inclined air showers is currently receiving great attention. To exploit the potential, a suitable event reconstruction needs to be developed. The first step in this direction is the development of a model for the lateral distribution of the radio signals, which in the case of inclined air showers exhibits asymmetries due to "early-late" effects in addition to the usual asymmetries from the superposition of charge-excess and geomagnetic emission. We present a model which corrects for all asymmetries and successfully describes the lateral distribution of the energy fluence with a rotationally symmetric function. This gives access to the radiation energy as a measure of the energy of the cosmic-ray primary, and is also sensitive to the depth of the shower maximum., Comment: To be published in the proceedings of the ARENA2018 conference; revised version with important fix of former equation (2)

Abstract: Radio emission from air showers enables measurements of cosmic particle kinematics and identity. The radio signals are detected in broadband Megahertz antennas among continuous background noise. We present two deep learning concepts and their performance when applied to simulated data. The first network classifies time traces as signal or background. We achieve a true positive rate of about 90% for signal-to-noise ratios larger than three with a false positive rate below 0.2%. The other network is used to clean the time trace from background and to recover the radio time trace originating from an air shower. Here we achieve a resolution in the energy contained in the trace of about 20% without a bias for $80\%$ of the traces with a signal. The obtained frequency spectrum is cleaned from signals of radio frequency interference and shows the expected shape., Comment: 20 pages, 13 figures, resubmitted to JINST

Abstract: The construction of the first stage of the Pierre Auger Observatory, designed for research of ultra-high energy cosmic rays, began in 2001 with a prototype system. The Observatory has been collecting data since early 2004 and was completed in 2008. The Observatory is situated at 1400 m above sea level near Malargue, (Mendoza province) in western Argentina, covering a vast plain of 3000 squared km, known as the Pampa Amarillo. The Observatory consists of a hybrid detector, in which there are 1660 water-Cherenkov stations, forming the Surface Detector (SD) and 27 peripheral atmospheric fluorescence telescopes, comprising the Fluorescence Detector (FD).Over time, the Auger Observatory has been enhanced with different R&D prototypes and is recently being to an important upgrade called AugerPrime. In the present contribution, the general operations of the SD and FD will be described. In particular the FD shift procedure - executable locally in Malargue or remotely by teams in control rooms abroad within the Collaboration - and the newly SD shifts (operating since 2019) will be explained. Additionally, the SD and FD maintenance campaigns, as well as the data taking and data handling at a basic level, will be reported

Abstract: Radio detection of inclined air showers currently receives special attention. It can be performed with very sparse antenna arrays and yields a pure measurement of the electromagnetic air-shower component, thus delivering information that is highly complementary to the measurement of the muonic component using particle detectors. However, radio-based reconstruction of inclined air showers is challenging in light of asymmetries induced in the radio-signal distribution by early-late effects as well as the superposition of geomagnetic and charge-excess radiation. We present a model for the signal distribution of radio emission from inclined air showers which allows explicit compensation of these asymmetries. In a first step, geometrical early-late asymmetries are removed. Secondly, a universal parameterization of the charge-excess fraction as a function of the air-shower geometry, the atmospheric density profile and the lateral distance from the shower axis is used to compensate for the charge-excess contribution to the signal. The resulting signal distribution of the pure geomagnetic emission is then fit with a rotationally symmetric lateral distribution function, the area integration of which yields the radiation energy as an estimator for the cosmic-ray energy. We present the details and performance of our model, which lays the foundation for robust and precise reconstruction of inclined air showers from radio measurements., Proceedings of the 36th ICRC, Madison, WI, USA, PoS(ICRC2019)294; v2 updated to final published version with slight changes of fit values in section 6 and Fig. 8 due to correction of a mixup
