Self-regulated Evolution of Galaxies and Supermassive Black Holes [abstract]

I will use results from the OverWhelmingly Large Simulations (OWLS) project to investigate the physics driving the growth of galaxies and supermassive black holes. Feedback from star formation and from accretion onto black holes can regulate the growth of low- and high-mass galaxies, respectively. This self-regulation has some counter-intuitive implications. For example, the galaxy star formation rate is insensitive to the star formation law and the mass of the black hole is insensitive to the efficiency of the AGN feedback. I will argue that the masses of supermassive black holes may be controlled by their host dark haloes rather than by their host stellar bulges. I will also argue that gaseous haloes of groups of galaxies are key to understanding the feedback processes relevant for galaxy formation and that these processes may work rather differently than typically assumed. Finally, I will show that baryonic physics affects the matter distribution out to much larger scales than previously thought.
