The Effects of AGN Feedback on Present-Day Galaxy Properties in Cosmological Simulations


We show that feedback from active galactic nuclei (AGN) plays an essential role in reproducing the down-sizing phenomena, namely: the colour-magnitude relation; specific star formation rates; and the α enhancement of early type galaxies. In our AGN model, black holes originate from Population iii stars, in contrast to the merging scenario of previous works… (More)
