Finding SMBH binaries with Tidal Disruption Events

Tidal disruption events (TDEs) provide an exciting opportunity to study supermassive black holes (SMBHs) in quiescent galaxies and the stellar populations and dynamics in galactic nuclei. They are also intimately connected to galaxy evolution. For example, their rates are dependent on star formation and are also expected to increase drastically after galaxy mergers in the presence of SMBH binaries. I will discuss how finding TDEs from the smaller black hole in a SMBH binary can help us uncover hidden SMBH binaries. I will then describe the rates and properties we would expect for these events. With upcoming large-scale transient surveys increasing our population of observed TDEs by orders of magnitude, we hope to use TDEs as a tool to find SMBH binaries in quiescent galaxies.
