New X-ray observations of a hybrid Narrow Line Seyfert 1 (NLS1) galaxy Mrk 1239 with joint NuSTAR and XMM-Newton in the 0.3-40.0 keV band are presented. Below 2 keV, direct AGN emission is obscured revealing a complex RGS spectrum rich in emission lines originating from a two-component plasma (collisionally and photoionized) at large distances from the black hole. The spectral variability below 3 keV is remarkably consistent over 20 years of observations. Above 3 keV the AGN dominates the emission and the NLS1 nature is revealed. A flaring event was captured with NuSTAR where the 4-30 keV count rate increased by a factor of 5 in a few kiloseconds before returning to near pre-flare levels just as quickly. Ionized partial covering and relativistic blurred reflection have previously been considered for the central region emission. Questions remain about the nature of the NuSTAR flare, and the continuum model for Mrk 1239., Preliminary work was presented at the 2022 XMM-Newton workshop.

Purpose: To examine cross-sectional associations between perceived neighborhood environment and cognitive function among middle-aged and older Hispanic/Latino women and men. Methods: Data from the Hispanic Community Health Study/Study of Latinos (2008–2011) and its Sociocultural Ancillary Study (2009–2010) were used. Participants were Hispanic/Latino women (n = 1812) and men (n = 1034) aged 45–74 years. Survey-weighted linear regression models were used to examine associations between self-reported perceived neighborhood environment (i.e., neighborhood social cohesion and problems categorized as quintiles, and neighborhood safety from crime categorized as low, medium, or high) with cognitive function (i.e., global cognition, verbal learning, memory, verbal fluency, and processing speed scores) in women and men. Final model adjusted for age, Hispanic/Latino background, language, field site, household income, education, years lived in neighborhood, and depressive symptoms. Results: Women in the lowest quintile of perceived neighborhood problems (vs. highest quintile) had higher global cognition (β 0.48, 95% CI 0.03, 0.94, p trend 0.229) and memory scores (0.60, 95% CI 0.11, 1.09, p trend: 0.060). Women in the highest quintile of perceived neighborhood social cohesion (vs. lowest quintile) had lower global cognition (β − 0.56, 95% CI − 1.02, − 0.09, p trend 0.004), verbal learning (B − 1.01, 95% CI − 2.00, − 0.03, p trend 0.015), verbal fluency (B − 2.00, 95% CI − 3.83, − 0.16, p trend 0.006), and processing speed (B − 2.11, 95% CI − 3.87, − 0.36, p trend 0.009). There was no association between perceived neighborhood safety from crime and cognition among women, or between any perceived neighborhood environment measure and cognition among men. Conclusions: Middle-aged and older Hispanic/Latina women living in neighborhoods with the lowest perceived problems had higher global cognition and memory. Women living in neighborhoods with the highest perceived social cohesion had lower global cognition, verbal learning, verbal fluency, and processing speed.

We present a spectral analysis of the narrow-line Seyfert 1 galaxy I Zwicky 1, focusing on the characteristics of the ionised absorbers as observed with XMM-Newton in 2005. The outflow velocity of the X-ray low-ionisation absorber is consistent with the outflow of the UV absorber detected in a past Hubble Space Telescope observation. In addition, the ionic column densities of Civ and Nv derived from the X-ray model are consistent with the UV values. This suggests that the low-ionisation outflowing gas may survive for many years, despite large changes in flux, and that there is a tight connection between the X-ray and UV absorbers that can only be confirmed with a simultaneous UV and X-ray observation.

The short-term spectral variability of the narrow-line Seyfert 1 galaxy I Zwicky 1 (I Zw 1) as observed in an 85ks XMM-Newton observation is discussed in detail. I Zw 1 shows distinct modes of variability prior to and after a flux dip in the broad-band light curve. Before the dip the variability can be described as arising from changes in shape and normalization of the spectral components. Only changes in normalization are manifested after the dip. The change in the mode of behaviour occurs on dynamically short time-scales in I Zw 1. The data suggest that the accretion-disc corona in I Zw 1 could have two components that are co-existing. The first, a uniform, physically diffuse plasma responsible for the `typical' long-term (e.g. years) behaviour; and a second compact, centrally located component causing the rapid flux and spectral changes. This compact component could be the base of a short or aborted jet as sometimes proposed for radio-quiet active galaxies. Modelling of the average and time-resolved rms spectra demonstrate that a blurred Compton-reflection model can describe the spectral variability if we allow for pivoting of the continuum component prior to the dip.
