Host galaxy properties of X-ray AGN in the Local Universe
L. Koutoulidis, G. Mountrichas, I. Georgantopoulos +2
We study the host galaxy properties of active galactic nuclei (AGN) that have been detected in X-rays in the nearby Universe (). For that purpose, we use the catalogue p…
The XXL Survey XXXII. Spatial clustering of the XXL-S AGN
M. Plionis, L. Koutoulidis, E. Koulouridis +9
The XMM-XXL Survey spans two fields of deg each observed for more than 6Ms with XMM, which provided a sample of tens of thousands of point sources with a flux limit of…
X-ray observations of dust obscured galaxies in the Chandra Deep Field South
A. Corral, I. Georgantopoulos, A. Comastri +6
We present the properties of X-ray detected dust obscured galaxies (DOGs) in the Chandra Deep Field South. In recent years, it has been proposed that a significant percentage of th…
Comparison of the spatial and the angular clustering of X-ray AGN
L. Koutoulidis, M. Plionis, I. Georgantopoulos +4
The angular correlation function is a powerful tool for deriving the clustering properties of AGN and hence the mass of the corresponding dark matter halos in which they reside. Ho…
The XMM spectral catalog of SDSS optically selected Seyfert 2 galaxies
E. Koulouridis, I. Georgantopoulos, G. Loukaidou +6
We present an X-ray spectroscopic study of optically selected (SDSS) Seyfert 2 (Sy2) galaxies. The goal is to study the obscuration of Sy2 galaxies beyond the local universe, using…
The XMM-Newton survey in the H-ATLAS field
P. Ranalli, I. Georgantopoulos, A. Corral +8
Wide area X-ray and far infrared surveys are a fundamental tool to investigate the link between AGN growth and star formation, especially in the low-redshift universe (z<1). The He…
Clustering, Bias and the Accretion Mode of X-ray selected AGN
L. Koutoulidis, M. Plionis, I. Georgantopoulos +1
We present the spatial clustering properties of 1466 X-ray selected AGN compiled from the Chandra CDF-N, CDF-S, eCDF-S, COSMOS and AEGIS fields in the 0.5-8 keV band. The X-ray sou…
