The QSOFEED project: a multi-wavelength view of AGN feedback impact on the central kpcs of galaxies

Abstract: Active galactic nuclei (AGN) winds and jets are potential drivers of multi-phase outflows and can significantly modify the interstellar medium (ISM) properties of their host galaxies. The Quasar Feedback (QSOFEED) project aims to investigate the impact of multi-phase quasar-driven outflows and jets on the nuclear regions of galaxies. These regions have dynamical timescales similar to the AGN activity lifetime and offer a way to assess the influence of the current AGN episode on the galaxy. Through a comprehensive analysis that combines high-resolution observations from cutting-edge facilities (e.g. ALMA, Keck, GTC, and Gemini) with contemporaneous galaxy properties and hydrodynamical simulations, the QSOFEED project provides insights into the efficiency and coupling of AGN outflows with host galaxies. Despite AGN feedback not depleting the gas reservoirs and quenching global star formation, our observations reveal that the radio jets/winds disturb the morphology, kinematics, and young stellar population distribution within the central kiloparsecs of galaxies. Moreover, our findings provide further evidence that the coupling between the jet and the ISM is relevant to AGN feedback, even in the case of radio-quiet galaxies.
