Since the 1990s, we have known that there is a super-massive black hole in every galaxy, and that its mass is proportional to the mass of the bulge. To better understand how these black holes were formed, in symbiosis with their galaxies, we will look at their demography, the scaling relations between properties of black holes and host galaxies, and their evolution in a Hubble time. Observations at high angular resolution now allow us to enter the black hole sphere of influence, to see the molecular tori evoked in the AGN unification paradigm, and to understand the feeding processes of black holes. These are often accompanied by feedback processes, which moderate the formation of galaxies. This is a graduate-student level lecture, not a review article.

  1. An (in)complete NIRSpec census of Balmer absorption in Type 1 AGN -- radiation-driven outflows in little red dots, quasars and variable stars

    astro-ph.GA 2026-07 conditional novelty 6.0 of 10

    About 44% of little red dots have hydrogen-alpha absorption from outflowing gas, implying radiatively driven outflows rather than static atmospheres.

  2. Echo mapping of the black hole accretion flow in NGC 7469

    astro-ph.GA 2025-06 conditional novelty 6.0 of 10

    New high-cadence reverberation mapping of NGC 7469 finds disc lags consistent with λ^(4/3) but about three times larger than standard predictions, with a possible steep dusty rim at about 7 light days.
