Anelise Audibert (Instituto de Astrofísica de Canarias), "QSOFEED: tracing AGN feedback across gas phases in obscured quasars"
Understanding how active galactic nuclei (AGN) shape their host galaxies requires tracing feedback across all phases of the interstellar medium. In this talk, I will present results from the QSOFEED project, a multi-wavelength study of nearby (z ? 0.1) obscured quasars designed to characterize AGN feedback across multiple gas phases. We are gathering high-resolution, multi-wavelength IFU observations tracing the ionized, warm, and cold molecular gas, using state-of-the-art facilities including JWST/MRS, ALMA, Keck, MEGARA, and SINFONI. These data reveal widespread disturbed kinematics and outflows on kiloparsec scales. A VLA radio continuum campaign further uncovers structured radio emission, including compact and galaxy-scale jets embedded within extended components. These jets, even at low radio powers, are increasingly recognized as important drivers of feedback in these systems. By combining these tracers with host galaxy properties and comparisons to hydrodynamical simulations, we are building a multi-phase view of AGN-driven feedback, where winds and jets act together to regulate the structure and kinematics of the interstellar medium in the host galaxies of obscured quasars.
