Constraining the fraction of Compton-thick AGN in the Universe by modelling the diffuse X-ray background spectrum
A. Akylas, A. Georgakakis, I. Georgantopoulos +2
This paper investigates what constraints can be placed on the fraction of Compton-thick (CT) AGN in the Universe from the modeling of the spectrum of the diffuse X-ray background (…

The evolution of the Compton thick fraction and the nature of obscuration for AGN in the Chandra Deep Field South
Murray Brightman, Yoshihiro Ueda
(Abridged) We present the results from the X-ray spectral analysis of high-z AGN in the CDFS, making use of the new 4Ms data set and new X-ray spectral models from Brightman & Nand…

X-ray colour-colour selection for heavily absorbed AGN
Murray Brightman, Kirpal Nandra
We present a method for the identification of heavily absorbed AGN (NH>10^23 cm^-2) from X-ray photometric data. We do this using a set of XMM-Newton reference spectra of local gal…
