New Connections Between Supermassive Black Holes and Host Galaxies

The accretion of individual stars by supermassive black holes can be observed when stars are torn apart through tidal forces, resulting in a bright observable flare. I will present recent work demonstrating that these tidal disruption events (TDEs) occur at a high rate in galaxies which have experienced a recent galaxy-wide burst of star formation. I will explore several possibilities for what might connect the small-scale dynamics at the centers of these galaxies to their large-scale star formation histories, and present a method for using this host galaxy preference to find new TDEs in next-generation large transient surveys.
