Abstract: Galaxies, on the hole Most, if not all, galaxies in the Universe contain a central supermassive black hole. The accretion of matter onto such black holes is thought to power luminous quasars, but little is know about how black holes interact with galaxies. Using simulations of galaxy formation that follow star formation, black hole growth and the associated feedback processes, Di Matteo et al. now show that galactic mergers lead to strong nuclear gas inflows, fuelling powerful starbursts and rapid growth of central black holes. Black holes also have a crucial impact on the formation of galaxies themselves, with the properties of remnant galaxies closely related to final black hole masses.
