Abstract

Context. The evidence of a decrease with increasing luminosity in the fraction fabs of absorbed and Compton-thin among X-ray-selected (2-10 keV) AGN is observationally well supported, while that of an increase in fabs with redshift is fairly controversial. In a previous paper, the gravitational effect of the SMBH on the molecular interstellar gas, in the central region of the host galaxy, was shown to predict an anti-correlation between fabs and the black-hole mass MBH.
