Weighing Black Holes using Tidal Disruption Events
  While once rare, observations of stars being tidally disrupted by
supermassive black holes are quickly becoming commonplace. To continue to learn
from these events it is necessary to robustly and systematically compare our
growing number of observations with theory. We present a tidal disruption
module for the Modular Open Source Fitter for Transients (MOSFiT) and the
results from fitting 14 tidal disruption events (TDEs). Our model uses FLASH
simulations of TDEs to generate bolometric luminosities and passes these
luminosities through viscosity and reprocessing transformation functions to
create multi-wavelength light curves. It then uses an MCMC fitting routine to
compare these theoretical light curves with observations. We find that none of
the events show evidence for viscous delays exceeding a few days, supporting
the theory that our current observing strategies in the optical/UV are missing
a significant number of viscously delayed flares. We find that the events have
black hole masses of $10^6 - 10^8 M_{\odot}$, and that the masses we predict
are as reliable as those based on bulk galaxy properties. We also find that
there is a preference for stars with mass $< 1 M_{\odot}$, as expected when
low-mass stars greatly outnumber high-mass stars.
