Compton-thick AGN in the NuSTAR era II: A deep NuSTAR and XMM-Newton view of the candidate Compton thick AGN in NGC 1358
X. Zhao, S. Marchesi, M. Ajello +4
We present the combined NuSTATR and XMM-Newton 0.6-79 keV spectral analysis of a Seyfert 2 galaxy, NGC 1358, which we selected as a candidate Compton thick (CT-) active galactic nu…
The XXL survey XXXV. The role of cluster mass in AGN activity
E. Koulouridis, M. Ricci, P. Giles +15
We present the results of a study of the AGN density in a homogeneous and well-studied sample of 167 bona fide X-ray galaxy clusters () from the XXL Survey. The results…
The XXL Survey: XXII. The XXL-North spectrophotometric sample and galaxy stellar mass function in X-ray detected groups and clusters
V. Guglielmo, B. M. Poggianti, B. Vulcani +42
The fraction of galaxies bound in groups in the nearby Universe is high (50% at z~0). Systematic studies of galaxy properties in groups are important in order to improve our unders…
The XXL Survey XIX. A realistic population of simulated X-ray AGN: Comparison of models with observations
E. Koulouridis, L. Faccioli, A. M. C. Le Brun +11
Modern cosmological simulations rely heavily on feedback from active galactic nuclei (AGN) in order to stave off overcooling in massive galaxies and galaxy groups and clusters. An…
The 2-10 keV unabsorbed luminosity function of AGN from the XMM-Newton LSS, CDFS and COSMOS surveys
P. Ranalli, E. Koulouridis, I. Georgantopoulos +15
The XMM-LSS, XMM-COSMOS, and XMM-CDFS surveys are complementary in terms of sky coverage and depth. Together, they form a clean sample with the least possible variance in instrumen…
X-ray properties of radio-selected star forming galaxies in the Chandra-COSMOS survey
P. Ranalli, A. Comastri, G. Zamorani +7
X-ray surveys contain sizable numbers of star forming galaxies, beyond the AGN which usually make the majority of detections. Many methods to separate the two populations are used…
Suzaku observations of hard X-ray selected Seyfert 2 galaxies
A. Comastri, K. Iwasawa, R. Gilli +4
We present Suzaku observations of five hard X-ray selected nearby Seyfert 2 galaxies. All the sources were clearly detected with the pin Hard X-ray Detector up to several tens of k…
The evolution of obscured accretion
R. Gilli, A. Comastri, C. Vignali +2
Our current understanding of the evolution of obscured accretion onto supermassive black holes is reviewed. We consider the literature results on the relation between the fraction…
