An HIPER view of AGN feedback on the gas reservoirs at cosmic noon

Active galactic nuclei (AGN) are thought to play a key role in shaping the buildup of galaxies. AGN-driven outflows could be responsible for efficient gas removal or heating and are now routinely detected at any redshift. At the same time, if AGN influence galaxy growth, then they will reasonably impact the molecular gas reservoir first, and star formation as a consequence. While convincing evidence that AGN hosts at cosmic noon (z~1-3) harbor reduced amounts of molecular gas mass compared to their non-AGN analogs is growing, we still have to pinpoint how such a reduction is set into place. The ERIS GTO program HIPER (High resolution Investigation of Feedback Processes with ERis; PI: G. Cresci) specifically aims at probing whether the level of molecular gas depletion is related to the properties, such as strength and velocity, of AGN-driven winds. I will present our most recent efforts in investigating causes and effects of AGN feedback on galaxies at cosmic noon, from gas depletion in AGN hosts to the properties of AGN-driven outflows as traced with new-generation instruments as JWST/NIRspec and VLT/ERIS.
