Active Galactic Nuclei (AGN) fueling and feedback


The feeding of super-massive black holes in galaxies is a problem that can be addressed now with high spatial resolution in nearby AGN. Dynamical mechanisms are essential to exchange angular momentum and drive the gas to the center. While at 100pc scale, the gas is sometimes stalled in nuclear rings, recent observations reaching ~10pc scale (or 50mas), inside the sphere of influence of the black hole, may bring smoking gun evidence of fueling, within a randomly oriented nuclear molecular disk. Observations of AGN feedback will be presented, together with the suspected responsible mechanisms. Molecular outflows are frequently detected in active galaxies, and the ALMA and NOEMA resolution gives clues to their origin, either radiative of kinetic AGN mode, or starburst. When driven by AGN with near escape velocity, these outflows are therefore a clear way to moderate or suppress star formation.
