DESCRIPTION:Speaker: Suvi Gezari\nhosted by Zoltan Haiman\nAbstract: Using 
 Tidal Disruption Events as Probes of Massive Black Hole Formation and Grow
 th Over Cosmic TimeAbstract: The tidal disruption of a star that wanders 
 too close to a central black hole is a unique probe of quiescent supermass
 ive black holes lurking in the nuclei of galaxies.  We have demonstrated 
 the ability to discover and spectroscopically classify large samples of ti
 dal disruption events (TDEs) in the optical from the Zwicky Transient Faci
 lity (ZTF) Northern Sky Survey\, with systematic high-energy follow-up wit
 h Swift and XMM-Newton. From these efforts\, we now know the spectroscopic
  signatures\, multi-wavelength properties\, and host galaxy preferences of
  TDEs\, and can begin to use them as powerful probes of massive black hole
  demographics in quiescent galaxies.  One of the most exciting applicatio
 ns of TDEs is the ability to probe intermediate mass black holes (IMBHs) t
 hat are expected to reside in dwarf galaxies\, with demographics that enco
 de the seeding mechanism of massive black holes in the early Universe.  I
  will outline our strategy in the next decade for searching for TDEs acros
 s the black hole mass function\, and over cosmic time\, by extending our s
 ensitivity to TDEs to lower central black hole masses and higher redshifts
 \, by exploiting the discovery power of the next generation of wide-field 
 time domain surveys\, including Rubin\, Roman\, ULTRASAT\, and UVEX.
