Title: Late-time Observations of Bright Tidal Disruption Events

Abstract: Dormant black holes at the centers of quiescent galaxies reveal themselves through luminous, accretion- powered flares called tidal disruption events (TDEs). These rare events, occuring roughly once every 10000 years in a Milky Way-type galaxy, provide unique insights into the physics associated with accretion and the black hole itself. Most studies of TDEs focus on the initial detection and follow-up of the flare, but recent late-time studies of TDE emission have revealed some surprises, including the presence of spectroscopic emission lines years after the disruption occurred. Here we propose to expand the sample of late-time spectra of TDEs and their hosts using LBT/MODS to observe some of the brightest and closest optical TDEs.
