Chandra and Spitzer observations of CDFS X-ray obscured QSOs
I. Georgantopoulos, A. Georgakakis, A. Akylas
We present Chandra and Spitzer data of the 186, extragalactic, hard 2-10 keV X-ray selected sources, which lie in the central part of the Chandra Deep Field South (CDFS). For the v…
XMM and Chandra measurements of the AGN intrinsic absorption: dependence on luminosity and redshift
A. Akylas, I. Georgantopoulos, A. Georgakakis +2
We combine bright XMM data with the Chandra Deep Field South observations in order to explore the behavior of the intrinsic AGN absorption, as a function of redshift and luminosity…
X-ray number counts of normal galaxies
A. Georgakakis, I. Georgantopoulos, A. Akylas +2
We use the number counts of X-ray selected normal galaxies to explore their evolution by combining the most recent wide-angle shallow and pencil-beam deep samples available. The di…
