Abstract

We investigate the cosmological evolution of the hard X-ray luminosity function (HXLF) of active galactic nuclei (AGNs) in the 2-10 keV luminosity range of 10 41.5 -10 46.5 ergs s 1 as a function of redshift up to 3. From a combination of surveys conducted at photon energies above 2 keV with HEAO 1,...
