SO Web-Colloquia: Following black hole evolution from z=5: mergers and outflows

The growth and evolution of the most massive black holes, and their host galaxies, can be followed from z=7 and even earlier. The critical events that shape this evolution are major mergers, Eddington or super-Eddington accretion, violent star formation, and powerful outflows. I will present the results of a systematic study of 40 AGN at z~4.8 using Gemini, VLT, Herschel and ALMA. Our recent (2019) ALMA data allow a fresh look at major mergers and their association, if any, with the most violent star formation in the early universe. I will also make a connection with our recent study of ionized AGN-driven outflows at lower redshifts and try to assess their efficiency in quenching star formation.
