Low accretion rates at the AGN cosmic downsizing epoch

Low accretion rates at the AGN cosmic downsizing epoch

Context: X-ray surveys of Active Galactic Nuclei (AGN) indicate `cosmic downsizing', with the comoving number density of high-luminosity objects peaking at higher redshifts (z about 2) than low-luminosity AGN (z<1). Aims: We test whether downsizing is caused by activity shifting towards...
