We present evidence that the incidence of active galactic nuclei (AGNs) and the distribution of their accretion rates do not depend on the stellar masses of their host galaxies, contrary to previous studies. We use hard (2-10 keV) X-ray data from three extragalactic fields (XMM-LSS, COSMOS and ELAIS-S1) with redshifts from the Prism Multi-object Survey to identify 242 AGNs with L_{2-10 keV}=10^{42-44} erg /s within a parent sample of ~25,000 galaxies at 0.2View original: http://arxiv.org/abs/1107.4368
