Beyond being Cosmic Beacons: Insights on the Role of Accreting Supermassive Black Holes in Galaxy Assembly from the Story at z~0
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 and its galaxy bulge, which in turn implies that the SMBHs play a significant role in regulating galaxy assembly. SMBHs grow via coalescence as a consequence of their host galaxies merging or due to accretion. Our current broad understanding is that the SMBHs 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. However, the exact mechanisms and the circumstances under which positive and negative feedback dominate remain elusive. I will describe a multi-frequency investigation of the imprints if any at very nearby redshifts of this feedback between the accretion around the SMBH and star formation in the host galaxy.
