Quasar Feedback Survey – the impact of jets and multi-phase outflows on their host galaxies

I will present an overview of the Quasar Feedback Survey (QFeedS) and will illustrate its powerful capabilities to establish the role of rapidly growing supermassive black holes (i.e., quasars) in galaxy evolution. Using spatially-resolved ionized gas and stellar kinematic measurements from MUSE data, molecular gas kinematics from ALMA data, and high-quality imaging from the VLA, we are measuring in exquisite detail how z<0.2 quasars interact with the host galaxy's interstellar medium (ISM). By combining these data, we can infer the feedback effects on the host galaxy: 1) there are clear signatures of the impact of radio jet-ISM interactions in both the ionized and molecular phases; 2) we observe outflowing, dense turbulent gas, perpendicular to the jet-axis, extending to galactic scales; 3) we observe evidence for jet-induced feedback on the stellar properties. Recent simulations of jet-ISM interactions, qualitatively agree with our observations; specifically, as inclined, low power jets move through the galaxy, they strongly interact with the ISM, causing highly turbulent material to be stripped, which then escapes above and below the galaxy disk. The overall impact is to both remove gas from the host galaxy (globally suppressing star formation) and to compress the gas (locally inducing star formation). Through my analysis, I present a discussion of how such jet-induced feedback could be an important, previously underappreciated, feedback mechanism for bolometrically luminous `radio quiet' quasars.
