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

Taylor, Philip; Kobayashi, Chiaki

Description

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. In this paper, we show how the properties of present-day galaxies in cosmological chemo-hydrodynamical simulations change when we...[Show more]
