Abstract: Operation of the central portion of Virgo as a simple 6 m Michelson interferometer has given the first demonstration of the possibility to control an interferometer suspended from Virgo full scale multistage seismic attenuators using information derived from the interferometer locking signal. A special role in the control is played by the first stage of these suspensions, an inverted pendulum: besides its seismic preisolation action, this stage has positioning dynamics of several mm, and it allows to exert a very low frequency control at the upper level of the suspension using the interferometer fringe signal. The application of this feedback to the top-stage of the suspension allows corrections of drifts, such as tidal ones, at a stage of the suspension where a large dynamic range in displacements is available, without introducing noise at the level of the mirror, resulting in a significant reduction of the lock keeping force applied directly on the mirror at the lowest stage of the attenuator.

Abstract: Large optical components (diameter 350 mm), having extremely low loss at 1064 nm, are needed for the large-scale Michelson-type interferometer VIRGO. Today, ion beam sputtering is the only deposition technique able to produce optical components having such performances. Consequently, a large ion beam sputtering deposition system was built to coat large optics up to 700 mm in diameter: two large substrates may also be coated at the same time for interferometer arm symmetry problem. The performances of this coater are described in terms of layer uniformity on a large scale (wavefront) and optical losses (absorption and scattering). The VIRGO interferometer needs six main mirrors. The first set was ready in June 2002 and they have been installed on the VIRGO site (Italy). The optical performances of this first set are discussed. The requirements at 1064 nm are all satisfied. Indeed, the absorption level is close to 1 ppm (part per million), the scattering is lower than 5 ppm and the RMS wavefront of these optics is lower than 8 nm on 150 mm in diameter. Finally, some solutions are proposed to further improve these performances, especially the absorption level and the mechanical quality factor Q of the mirrors and the substrate wavefront before coating.

Abstract: We have analysed three data sets, each two days long, of the EXPLORER resonant bar detector. We have searched for continuous gravitational-wave signals from spinning neutron stars. Our data analysis technique was based on the maximum likelihood detection method. We briefly describe the theoretical methods that we used in our search and we present results of the search. The main outcome of our analysis is an upper limit of 1 × 10 −22 for the dimensionless amplitude of a continuous gravitational-wave signal. The upper limit is for any source location in the sky, any polarization of the wave and for signals of frequency from 921.00 Hz to 921.76 Hz and with spin down from −2.36 × 10 −8 Hz s −1 to +2.36 × 10 −8 Hz s −1 .

Abstract: This paper presents a complete description of Virgo, the French-Italian gravitational wave detector. The detector, built at Cascina, near Pisa (Italy), is a very large Michelson interferometer, with 3 km-long arms. In this paper, following a presentation of the physics requirements, leading to the specifications for the construction of the detector, a detailed description of all its different elements is given. These include civil engineering infrastructures, a huge ultra-high vacuum (UHV) chamber (about 6000 cubic metres), all of the optical components, including high quality mirrors and their seismic isolating suspensions, all of the electronics required to control the interferometer and for signal detection. The expected performances of these different elements are given, leading to an overall sensitivity curve as a function of the incoming gravitational wave frequency. This description represents the detector as built and used in the first data-taking runs. Improvements in different parts have been and continue to be performed, leading to better sensitivities. These will be detailed in a forthcoming paper. © 2012 IOP Publishing Ltd and Sissa Medialab srl.

Abstract: The commissioning of the VIRGO central interferometer occasioned the implementation and tests of various algorithms for the characterization of the non-Gaussianity, non-stationarity and non-linearity of the dark fringe data. This library of prototypes will serve as groundwork for the near commissioning of VIRGO (full scale). We make a summary of the activities on that subject including the description of the selected algorithms and some results obtained with the data of the engineering runs.

Abstract: The full-sky incoherent step is the most computationally heavy in the hierarchical procedure developed in the search for continuous gravitational signals in the data of the Virgo detector. This step is based on the Hough transform. We have implemented it by means of an approach that uses look-up tables. Here, after a short introduction to the whole data analysis method, we describe the implementation of the Hough transform and discuss the performances of the code. Then, we discuss the computing framework in which data analysis will be performed. In particular, we briefly describe the architecture of the European DataGrid software, which we have used to deploy a small computational 'grid'. In this 'grid' environment we have tested our code and the results are shown.

Abstract: The interferometric gravitational wave detectors represent the ultimate evolution of the classical Michelson interferometer. In order to measure the signal produced by the passage of a gravitational wave, they aim to reach unprecedent sensitivities in measuring the relative displacements of the mirrors. One of them, the 3-km-long Virgo gravitational wave antenna, which will be particularly sensitive in the low-frequency range (10-100 Hz), is presently in its commissioning phase. In this paper the various techniques developed in order to reach its target extreme performance are outlined.

Abstract: SELECTED PAPERS FROM THE 6TH EDOARDO AMALDI CONFERENCE ON GRAVITATIONAL WAVES, OKINAWA, JAPAN, 20-24 JUNE 2005; International audience; The automatic alignment system of the Virgo interferometer differs substantially from those used in similar experiments, since it uses a variant of the Anderson technique. This implies a completely different control topology with respect to other detectors, and the main feature is a strong coupling of different degrees of freedom in the optical signals. It also provides two extra output ports in which differential wave-front sensors can be placed, namely the light transmitted by the Fabry–Perot arm cavities. We report on the first experimental demonstration of this technique on a large scale recycled interferometer, and on the present status of the automatic alignment system.

Abstract: We report on the status of the Virgo detector, under commissioning. We will focus on the last year's activity. The two commissioning runs performed during 2005 allowed us to reach a sensitivity ofh∼ 6 × 10−22. The data obtained during the runs were used to test a few data analysis algorithms, namely coalescing binaries and burst searches. The main improvements made on the detector during this year will be described, as well as the plans and activities foreseen in the coming years.

Abstract: International audience; The analysis of data taken during the C7 VIRGO commissioning run showed strong deviations from Gaussian noise. In this work, we explore a family of distributions, derived from the hypothesis that heavy tails are an effect of a particular kind of nonstationarity, heterocedasticity (i.e. nonuniform variance), that appear to fit VIRGO noise better than a model based on the assumption of Gaussian noise. To estimate the parameters of the noise process (including the heterogeneous variance) we derived an expectation-maximization algorithm. We show the consequences of non-Gaussianity on the fitting of autoregressive filters and on the derivation of test statistics for matched filter operation. Finally, we apply the new noise model to the fitting of an autoregressive filter for whitening of data.

Abstract: SELECTED PAPERS FROM THE 6TH EDOARDO AMALDI CONFERENCE ON GRAVITATIONAL WAVES, OKINAWA, JAPAN, 20-24 JUNE 2005; International audience; We present the status of the Virgo analysis pipeline dedicated to the search for coalescing binary signals, focusing on methods based on prior knowledge of the signal waveform. The pipeline includes two partially independent search methods: the multi-band template analysis (MBTA), which is original of Virgo and exploits the chirping behaviour of the signal, and a distributed implementation of the classical matched filter procedure (Merlino), based on robust MPI code. We discuss the application of the search methods to the analysis of data acquired during the Virgo commissioning run C5, which allowed us to perform tests and partially validate the methods and code.

Abstract: The study of the external influences from environmental disturbances is a fundamental issue in interferometric detection of gravitational wave, both in locking and in normal operation. Virgo is continuously monitored by a large number of environmental sensors, ranging from seismometers to microphones to electromagnetic probes, up to a weather station. Using data collected during the engineering runs, we have studied the features of the main external noise sources, and the way they interfere with Virgo operation and expected sensitivity. In this paper we present the preliminary results obtained.

Abstract: The gravitational wave detector VIRGO aims at extending the detection band down to a few Hertz by isolating the mirrors of the interferometer from seismic noise. This result is achieved by hanging each mirror through an elastic suspension (Superattenuator), designed to filter mechanical vibrations in all the degrees of freedom. An experimental upper limit of the mirror residual seismic noise at a few Hertz is provided in this paper. This is lower than the thermal noise floor, expected to limit the antenna sensitivity in the low frequency range.

Abstract: The goal of the VIRGO program is to build a giant Michelson type interferometer (3 kilometer long arms) to detect gravitational waves. Large optical components (350 mm in diameter), having extremely low loss at 1064 nm, are needed. Today, the Ion beam Sputtering is the only deposition technique able to produce optical components with such performances. Consequently, a large ion beam sputtering deposition system was built to coat large optics up to 700 mm in diameter. The performances of this coater are described in term of layer uniformity on large scale and optical losses (absorption and scattering characterization). The VIRGO interferometer needs six main mirrors. The first set was ready in June 2002 and its installation is in progress on the VIRGO site (Italy). The optical performances of this first set are discussed. The requirements at 1064 nm are all satisfied. Indeed, the absorption level is close to 1 ppm (part per million), the scattering is lower than 5 ppm and the R.M.S. wavefront of these optics is lower than 8 nm on 150 mm in diameter. Finally, some solutions are proposed to further improve these performances, especially the absorption level (lower than 0.1 ppm) and the mechanical quality factor Q of the mirrors (thermal noise reduction).

Abstract: We present the last-stage suspension for the mirrors of the gravitational wave antenna Virgo. We studied some problems encountered during the commissioning of the Virgo central interferometer (CITF) and solved them with the aim of achieving the target sensitivity of the detector in its final configuration. We measured the effect of the holder on the internal motion of the mirror, and the residual nonlinear couplings between the electromagnetic actuators and the metallic parts present on the last-stage suspension. The limits experienced on the Virgo CITF have helped us to define some important modifications to be applied to the last-stage suspension. Moreover, we present the experimental study of west input mirror internal modes after it was dismounted from the Virgo central interferometer. The results were useful to identify, in the data of the engineering run 4 of the CITF, the thermal peaks of such a mirror.

Subjects: Engineering, business.industry, Oil spill, Nozzle, Environmental engineering, Pilot scale, Biological optimization, Intertidal zone, Sediment, business
Abstract: This document summarizes the findings of a pilot study that was designed to determine biologically optimum cleaning parameters. The objectives of this ongoing study are (1) to determine the biological effects on intertidal biota associated with the use of hydraulic cleaning techniques, and (2) to develop data on environmentally optimum combinations of hydraulic cleaning parameters for use by oil spill responders. The laboratory/pilot scale phase of the project was conducted at the Bamfield Marine Station on Barkley Sound, British Columbia, in the fall of 1995. The hydraulic cleaning parameters examined were (1) water pressures ranging from deluge or minimal pressure to approximately 345 kPa (50 psi), (2) water temperatures ranging from ambient temperature to 80 C, and (3) nozzle angles of 45 degrees and 90 degrees to the substratum. Both oiled and unoiled trials were conducted. Treatment combinations of these parameters were delivered using a pressure washer connected to a constructed washing apparatus. The biological effects produced by the treatments were examined in attached organisms colonizing cobbles collected from a donor beach in Barkley Sound. Species tested included the algae Fucus spp. and Mastocarpus papillatus; the barnacles Chthamalus dalli and Balanus glandula; and limpets in the family Lottiidae. Among the main findings of the laboratory/pilot study were the following: (1) both mortalities and oil removal efficiencies were found to rise most rapidly from low to high levels between 40° and 60°C, and between 18.6 and 60 kPa (2.7 and 8.7 psi); (2) oiled trials were found to produce greater mortalities than unoiled trials; and (3) 90-degree nozzle angles were found to produce greater mortalities in some cases than 45-degree nozzle angles.

Abstract: The search procedure for burst gravitational waves has been studied using 24 hours of simulated data in a network of three interferometers (Hanford 4-km, Livingston 4-km and Virgo 3-km are the example interferometers). Several methods to detect burst events developed in the LIGO Scientific Collaboration (LSC) and Virgo collaboration have been studied and compared. We have performed coincidence analysis of the triggers obtained in the different interferometers with and without simulated signals added to the data. The benefits of having multiple interferometers of similar sensitivity are demonstrated by comparing the detection performance of the joint coincidence analysis with LSC and Virgo only burst searches. Adding Virgo to the LIGO detector network can increase by 50% the detection efficiency for this search. Another advantage of a joint LIGO-Virgo network is the ability to reconstruct the source sky position. The reconstruction accuracy depends on the timing measurement accuracy of the events in each interferometer, and is displayed in this paper with a fixed source position example., Comment: LIGO-Virgo working group submitted to PRD

In order to test the search programs, numerous inspiral signals were added to 24 hours of simulated detector data. The efficiencies of the different pipelines were tested, and found to be comparable. Parameter estimation routines were also tested. We demonstrate that there are definite benefits to be had if LIGO and Virgo conduct a joint coincident analysis; these advantages include increased detection efficiency and the providing of source sky location information., Comment: LIGO-Virgo Working Group.

Abstract: The gravitational wave detector VIRGO is in the final commissioning phase and some preliminary data has already been acquired. The aim of VIRGO is to directly detect gravitational waves emitted by compact objects at the time of coalescence and by other astrophysical sources. Here we report on the present sensitivity for detecting these sources and what we will achieve in the near future. We also discuss some details of our data analysis methods and we show some preliminary results related to the fraction of the Universe that we can observe.

Abstract: We present the result of a search for coincidences among the triggers found in the analysis of three 2-day-long stretches of data from the EXPLORER bar detector. The data were searched for nearly periodic gravitational waves from rapidly rotating neutron stars in our Galaxy. In this paper we propose a numerical procedure to search for coincidences and we present a theoretical formula for the expected number of coincidences. Our numerical analysis revealed no double and consequently no triple coincidences among the triggers from the three data sets. The results are in agreement with the expected number of coincidences that we estimate by our theoretical formula.

Abstract: The interferometric gravitational wave detector Virgo is currently completing its commissioning phase and it is close to start scientific observations. Among the signals to be searched for, those emitted by coalescing binary systems are particularly promising and require a considerable computational effort to optimally search the parameter space. The Virgo collaboration has decided to implement an on-line analysis strategy capable of processing the interferometer data in-time. In this communication we present a component of the analysis pipeline, a parallel computing system based on the Message Passing Interface (MPI). We describe its capabilities, underlining its strength and flexibility, and we illustrate its relation with the other components of the pipeline. The on-line analysis chain, including the presented parallel system, has been run for the first time successfully during the Virgo commissioning run C5 in December 2nd to December 6th 2004.

Abstract: We examine the benefits of performing a joint LIGO--Virgo search for transient signals. We do this by adding burst and inspiral signals to 24 hours of simulated detector data. We find significant advantages to performing a joint coincidence analysis, above either a LIGO only or Virgo only search. These include an increased detection efficiency, at a fixed false alarm rate, to both burst and inspiral events and an ability to reconstruct the sky location of a signal., Comment: 11 pages 8 figures, Amaldi 6 proceedings

Abstract: We present a comparative study of 6 search methods for gravitational wave bursts using simulated LIGO and Virgo noise data. The data's spectra were chosen to follow the design sensitivity of the two 4km LIGO interferometers and the 3km Virgo interferometer. The searches were applied on replicas of the data sets to which 8 different signals were injected. Three figures of merit were employed in this analysis: (a) Receiver Operator Characteristic curves, (b) necessary signal to noise ratios for the searches to achieve 50 percent and 90 percent efficiencies, and (c) variance and bias for the estimation of the arrival time of a gravitational wave burst., Comment: GWDAW9 proceedings

Abstract: The Alpha Magnetic Spectrometer (AMS) was flown on the space shuttle Discovery during flight STS-91 (June 1998) in a 51.7 deg orbit at altitudes between 320 and 390 km. A search for antihelium nuclei in the rigidity range 1–140 GV was performed. No antihelium nuclei were detected at any rigidity. An upper limit on the flux ratio of antihelium to helium of < 1.1×10^−6 was obtained. The high energy proton, electron, positron, helium, antiproton and deuterium spectra were accurately measured. For each particle and nuclei two distinct spectra were observed: a higher energy spectrum and a substantial second spectrum. Positrons in the second spectrum were found to be much more abundant than electrons. Tracing particles from the second spectra shows that most of them travel for an extended period of time in the geomagnetic field, and that the positive particles (p and e+) and negative ones (e−) originate from two complementary geographic regions. The second helium spectrum flux over the energy range 0.1–1.2 GeV/nucleon was measured to be (6.3 ± 0.9) × 10^−3(m^2 s sr)^−1. Over 90 percent of the helium flux was determined to be 3He at the 90% confidence level

Abstract: The lepton spectra in the kinetic energy ranges 0.2 to 40 GeV for e − and 0.2 to 3 GeV for e + were measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS–91 at altitudes near 380 km. From the origin of the leptons two distinct spectra were observed: a higher energy spectrum and a substantial second spectrum with positrons much more abundant than electrons. Tracing leptons from the second spectra shows that most of these leptons travel for an extended period of time in the geomagnetic field and that the e + and e − originate from two complementary geographic regions.

Abstract: The helium spectrum from 0.1 to 100 GeV/nucleon was measured by the Alpha Magnetic Spectrometer (AMS) during space shuttle flight STS-91 at altitudes near 380 km. Above the geomagnetic cutoff the spectrum is parameterized by a power law. Below the geomagnetic cutoff a second helium spectrum was observed. In the second helium spectra over the energy range 0.1 to 1.2 GeV/nucleon the flux was measured to be (6.3±0.9)×10 −3 ( m 2 sec sr ) −1 and more than ninety percent of the helium was determined to be 3He (at the 90% CL). Tracing helium from the second spectrum shows that about half of the 3He travel for an extended period of time in the geomagnetic field and that they originate from restricted geographic regions similar to protons and positrons.

39. Chromatophore Organs, Reflector Cells, Iridocytes and Leucophores in Cephalopods

Abstract: The chromatophore organs of Lohgo are each composed of five types of cells: a central pigment cell: radially arranged, obliquely striated muscle fibers: neuronal processes; glial cells: and an investment of sheath cells. Sheath cells are absent in Octopus chromatophore organs. The cycle of expansion and retraction of a chromatophore organ may occur within the order of a second. It is clear that the muscle fibers expand the pigment cell and spread out the pigment granules. The pigment is contained within an unusual, filamentous, cytoplasmic compartment called the cytoelastic sacculus. This compartment has elastic properties. Reflector cells and iridocytes produce structural colors even though their components are colorless. Reflector cells in Octopus bear peripheral sets of leaf-like reflecting lamellae called reflectosomes: these contain proteinaceous platelets with a high refractive index (1.42). In each reflectosome the reflecting lamellae are separated by gaps that are about equal to the thickness of the lamellae, but have a lower refractive index (1.33). Reflectosomes are believed to reflect light and to function as thin-film interference devices. Iridocytes in squid and cuttlefish contain iridosomes that are also composed of sets of ribbon-like platelets but these are located centrally within the cell body. The platelets are usually oriented on edge with respect to the surface of the skin. The possibility that dermal iridocytes may act as diffraction gratings is discussed. Leucophores have thousands of processes that contain globules of protein with a high refractive index. These cells scatter light of all wave lengths and appear white in white light.

Abstract: Kolliker's tufts are transient epidermal bristles found on the external surfaces of late embryonic and juvenile octopods. The structure and growth of Kolliker's tuft is remarkably similar to that of polychaete setae. Each tuft is a fasicle of approximately 1500 distally tapered cannular rodlets located in an epidermal follicle composed of several lateral follicular cells and a single basal chaetoblast. The base of the follicle is associated with obliquely striated dermal muscle fibers. Together these elements comprise Kolliker's organ. The rodlets, composed of longitudinally oriented filaments, are separated basally from one another by a layered meshwork of interstitial filaments. Microvilli on the apical concave surface of the scyphate chaetoblast insert into the base of each rodlet. We infer that the tuft elongates by basal appositional growth and that glycoprotein secreted by the follicle cells is organized into filaments by the apical plasmalemma of the chaetoblast. Each microvillus serves as a template for the formation of a rodlet, therefore the number, size, shape, distribution and dynamic activity of the microvilli determine the morphology of the tuft.

Abstract: The cells that form the reflecting layer beneath the chromatophore organs of the octopus are conspicuous elements of its dermal chromatic system. Each flattened, ellipsoidal reflector cell in this layer bears thousands of peripherally radiating, discoidal, reflecting lamellae. Each lamella consists of a proteinaceous reflecting platelet enveloped by the plasmalemma. The lamellae average 90 nm in thickness and have variable diameters with a maximum of about 1.7 micrometer. Sets of reflecting lamellae are organized into functional units called reflectosomes. The lamellae in each reflectosome form a parallel array - similar to a stack of coins. The average number of lamellae in a reflectosome is 11. Adjacent lamellae are uniformly separated by an extracellular gap of about 60 nm in embedded specimens. The reflectosomes are randomly disposed over the surface of the reflector cell. The observed organization of the reflectosomes is compatible with its role as a quarter-wave thin-film interference device. The alternating reflecting lamellae and intelamellar spaces constitute layers of high and low refractive indices. Using measurements of the thicknesses and refractive indices of the platelets and interlamellar spaces, we have calculated that the color of reflected light should be blue - green, as seen in vivo. The sequence of events leading to the definitive arrangement of the reflectosomes is uncertain. The reflector cells of O. dofleini are compared and contrasted with the iridophores of squid.

Abstract: The parenchymal components of rat submandibular gland were examined by scanning electron microscopy after removal of the stromal connective tissue by acid hydrolysis and/or enzymatic digestion. Secretory acini have polymorphous topographies but usually consist of three to five truncated lobes emanating from a common hilus. They have a mean volume of about 33,000 micrometers3. Myoepithelial cells are associated with the deeper acini of the gland where they cover congruent to 54% of the surface area of their allied acini. Each flattened myoepithelial cell has a central perikaryon that gives rise to four or five broad primary processes that bifurcate two or three times to produce a total complement of 20 to 40 terminal processes per cell, each 0.5 micrometer to 1.7 micrometers wide. The terminal processes of adjacent myoepithelial cells tend to slightly overlap and to attach to each other by desmosomes forming a network over adjacent acini. The components of the duct system are examined and each characterized by salient features as observed with the SEM.

Abstract: We present an experiment performed to study the behaviour of the dynamic gravitational in- teraction at laboratory scale. We used as eld generator a mass quadrupole rotating in the range of 460 Hz and we detected the acceleration eld with the cryogenic gravitational wave antenna Explorer of the Rome group. We report the measurements of this interaction as a function of the distance between the eld source and the detector. An upper limit on the parameters of a Yukawa-like potential, modeling an hypotetic deviation from the Newtonian law of gravity, is derived.

47. A comparison of methods for gravitational wave burst searches from LIGO and Virgo.

Abstract: The search procedure for burst gravitational waves has been studied using 24 h of simulated data in a network of three interferometers (Hanford 4 km, Livingston 4 km and Virgo 3 km are the example interferometers). Several methods to detect burst events developed in the LIGO Scientific Collaboration (LSC) and Virgo Collaboration have been studied and compared. We have performed coincidence analysis of the triggers obtained in the different interferometers with and without simulated signals added to the data. The benefits of having multiple interferometers of similar sensitivity are demonstrated by comparing the detection performance of the joint coincidence analysis with LSC and Virgo only burst searches. Adding Virgo to the LIGO detector network can increase by 50% the detection efficiency for this search. Another advantage of a joint LIGO-Virgo network is the ability to reconstruct the source sky position. The reconstruction accuracy depends on the timing measurement accuracy of the events in each interferometer, and is displayed in this paper with a fixed source position example.

Abstract: Presented in this paper is a detailed and direct comparison of the detection pipelines used by LIGO and Virgo in their attempt to observe gravitational waves from binary neutron star systems. In order to test the search programs, numerous inspiral signals were added to 24 h of simulated detector data. The efficiencies of the different pipelines were tested, and found to be very similar. Parameter estimation routines were also tested. We demonstrate that there are definite benefits if LIGO and Virgo conduct a joint coincident analysis; these advantages include increased detection efficiency and information on source sky location.
