Title: Do AGN Outflows Support Negative Feedback?
Cycle: 25

Abstract
Radiation, winds, and jets of Active Galactic Nuclei (AGN) have been shown to interact with their host galaxy interstellar medium. This radiative or quasar mode of feedback is thought to play a large role in terminating star formation in the galaxy and the accretion of matter onto the central supermassive black hole, accounting for the observed correlation between central black hole and host bulge mass. Recent IFU observations of the nearby Seyfert 2 AGN Mrk 573 have shown that gas radiatively driven by the central engine only travels to radii of approximately 750pc, much smaller than what would be required to evacuate gas from the host bulge. Using archival HST imaging and spectroscopy, we propose to perform similar kinematic analyses on a sample of 23 additional, nearby Seyfert AGN. By generating radiative driving models and comparing them to the observed ionized-gas kinematics in each target, we will determine the maximum outflow radii of the ionized gas and whether these outflows are of scales that would be required in successful negative feedback scenarios.
