Abstract:  When a star passes close enough to a massive black hole, the tidal forces across the star may exceed its self-gravity, causing a tidal disruption event (TDE).  The debris of the disrupted star accretes rapidly onto the black hole, generating a luminous flare which may rival quasars in brightness for months or years.  Although TDEs represent a promising method to investigate the population of (normally) quiescent massive black holes in the era of large synoptic surveys, an observationally-based understanding of TDE physics is necessary to interpret large datasets which are fundamentally photometric.  I will discuss findings from observations of long-term monitoring of bright, nearby TDEs, which can act as direct probes of black hole accretion from super-Eddington rates to quiescence in a normally quiescent environment.
