"Who's Afraid of the Big Bad Supermassive Black Hole?"

Supermassive black holes (SMBHs) are now known to be ubiquitous, with one present in the center of essentially every galaxy. The energy released by accretion onto an SMBH in the AGN phase is enough to not only outshine its host galaxy, but also to completely unbind the gas and rapidly quench star formation. But do SMBHs actually play an explosive role in galaxy evolution? In most cases, no! I will use a variety of observations - with careful consideration of selection effects - to demonstrate that AGN host galaxies are not particularly special. SMBH growth requires neither massive hosts nor violent angular momentum transport (i.e. mergers, disk instabilities, or large-scale bars). Instead AGNs are generally passengers on the road of galaxy evolution, fueled by the same gas reservoirs which drive star formation.
