AGN feedback studies at z~2: combining SINFONI and ALMA

Vincenzo MAINIERI
(ESO)

Theoretical models of AGN radiative feedback predict that AGN-driven, galaxy wide massive outflows are not a rare and peculiar phenomenon, but a fundamental process affecting the bulk of the baryons in the universe. Currently, sparse observational evidence of AGN feedback exists at z>1 but mostly limited to high luminosity objects, therefore a comprehensive picture is still far from being reached. SUPER is a SINFONI Large Programme at ESO aimed at carrying out the first statistically-sound investigation of ionized outflows in AGN host galaxies at the peak epoch of AGN and galaxy assembly, z~2. SUPER is designed to map the ionized gas kinematics ([OIII], Ha, Hb) with ~1 kpc spatial resolution, by exploiting the SINFONI AO capabilities, in a sample probing four orders of magnitude in AGN bolometric luminosity. I will report our current results on the ionized gas phase from this survey. I will also show the on-going follow up of the SUPER targets with ALMA, to trace the molecular gas content in the host galaxies.
