Hyperfine Temporal & Spatial Resolution of Stellar Ages amid Quasar-Driven gas flows: Unifying HST with MUSE and ALMA

The Close AGN Reference Survey (CARS; www.cars-survey.org) has assembled a rich, hyperdimensional dataset for 33 nearby Type 1 AGN, anchored by VLT/MUSE IFU datacubes for every target, along with pan-chromatic complementary datasets including ALMA for a large subset of the sample. We now propose an orders-of-magnitude increase in the spatial and temporal resolution of young stars and their ages (respectively) for the entire sample. The proposed WFC3/UVIS UV imaging will map sites of very recent star formation along multiphase quasar-driven outflows, instability-driven gas inflows, and merger-driven tidal interactions, testing whether each might lead to the suppression or even triggering of star formation. It is, therefore, a direct test of both negative and positive black hole feedback models.
