Abstract:
Supermassive black holes appear to inhabit the centres of most
galaxies and co-evolve with them, thus playing a significant role in
regulating galaxy assembly. We are able to spot these black holes to
very high redshifts when they accrete matter, which is also what
causes them to impact their environments out to spatial scales that
are well beyond their gravitational sphere of influence. In this talk
I will discuss the understanding that has emerged from
multiple-frequencies studies of the systematics of accreting
supermassive black holes.
