Descripción
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 quasar host galaxies. These regions have dynamic 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, JWST, 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. Based on the resolved analysis of multi-phase gas kinematics and stellar population synthesis, I will present our latest results on how feedback from outflows influences star formation and the ISM in a sample of radio-quiet quasars at z~0.1. I will also discuss preliminary results from our JWST program to study the impact of multi-phase outflows on recent star formation, as traced by polycyclic aromatic hydrocarbon molecules. We find evidence that AGN feedback is not depleting gas reservoirs or suppressing global star formation. Still, our observations reveal that the radio jets/winds strongly disturb the morphology, kinematics, and distribution of young stellar populations (ages < 100 Myr) within the central kiloparsecs of galaxies. These results highlight the importance of the jet-ISM interaction in the AGN feedback, even in the context of radio-quiet galaxies.
