Title: Active Galactic Nuclei: fueling and feedback
Abstract: Dynamical mechanisms are essential to exchange angular momentum in galaxies, drive the gas to the center, and fuel the central super-massive black holes. While at 100pc scale, the gas is sometimes stalled in nuclear rings,
recent observations reaching 10pc scale, or 60mas with ALMA, have revealed, within the sphere of influence of the black hole, smoking gun evidence of fueling. Observations of AGN feedback will be described, together with the

Star-forming galaxies form on the main-sequence as rotation dominated systems such that their angular momentum is a fundamental property. I will present the latest results on the specific angular momentum of
