Some Angles on the Systematics of Accreting Supermassive Black Holes

Supermassive black holes (SMBH) that are found in the centres of most galaxies comply with scaling relationships that imply hand-in-hand growth of the SMBH with galaxy bulge, which in turn implies that the SMBH play a significant role in regulating galaxy assembly. Our current understanding is that they influence star formation via the consequences of accretion, which enables them to impact their environments out to spatial scales that are well beyond their gravitational sphere of influence. In this talk I will discuss a few select results from investigating the systematics of accreting supermassive black holes at multiple frequencies and scales, and the understanding that has emerged from those investigations.
