Searching for Wandering MHBs and Stornly Lensed Transients in the Ear of Rubin, Roman, and Euclid

The Euclid and Roman wide-field surveys conicide with an exciting new era for transient discovery, in which Rubin Observatory's LSST will indentify thousands of tidal disruption events (TDEs) and millions of supernovae - including hundreds of gravitationally lensed supernovae (gLSNe).  These surveys will enable us to identify populations of transients that are only rarely detected in shallower time-domain surveys, including wandering MPHs spatially offset from their host nuclei that constrain MBH merger rates, and gLSNe from which we can estimate the Hubble Constant.  I will discuss how joint analysis of ground and space-based survey data via multi-resolution forward modeling methods will leverage time-domain information from LSST and high-resolution information from space for the identification of spatially offset TDEs and gLSNe.  I will also briefly discuss how optical and radio time-domain surveys are enabling us to study state-changing AGN as probes of super-Eddington accretion and the duty cycle of SMBH growth.
