The evolution of high-redshift massive black holes

Understand

Massive black holes (MBHs) are nowadays recognized as integral parts of galaxy evolution.

• Both the approximate proportionality between MBH and galaxy mass, and the expected importance of feedback from active MBHs in regulating star formation in their host galaxies point to a strong interplay between MBHs and galaxies.
• MBHs must form in the first galaxies and be fed by gas in these galaxies, with continuous or intermittent inflows that, at times, can be larger than the Eddington rate.
• Feedback from supernovae and from the MBHs themselves modulates the growth of the first MBHs.
