Abstract

Supermassive black holes (SMBHs) grow at the centre of galaxies in consonance with them. In this talk, I will first discuss observational signatures of the mass-feeding mechanisms that lead to this growth in active galactic nuclei (AGNs), from extragalactic down to galactic and nuclear scales. Once triggered, the nuclear activity produces feedback in the form of radiation, mass outflows and jets associated with the accretion flow to the SMBH. I will then concentrate on results from resolved Integral Field Spectroscopic (IFS) studies, including those of my research group AGNIFS. Most observational signatures of feeding and feedback processes in such studies are detected via the isolation of non-circular gas motions -- inflows and outflows that can be used to gauge the mass budget of the AGN feeding and the power and impact of gas outflows on the host galaxy. I will also discuss the uncertainties that plague the determination of this impact, that include uncertainties on the geometry and extent of the outflows as well as of the gas density in the outflows.
