Colin Burke -- Intermediate-mass black hole demographics with the Rubin Observatory
Optical variability is a powerful probe of the population of accreting black holes. Thanks to its superb cadence and depth, Rubin light curves will open a new window onto the population of accreting intermediate-mass black holes (IMBHs). In this talk, I will describe plans to develop and apply Bayesian modeling techniques to constrain the number density of IMBHs with early Rubin data. With Rubin light curves, IMBHs will also be laboratories for studying the physics of black hole accretion on human timescales.

Darryl Zachary Seligman -- Prospects for Interstellar Interlopers and Dark Comets with the Rubin Observatory
In recent years, two entirely new classes of planetesimals have been discovered in the solar system: interstellar interlopers and dark comets.  These still-enigmatic objects are challenging our understanding of the behavior and properties of comets and asteroids. In this talk, I will review what has been learned to date from the known interstellar objects and dark comets, highlighting the attributes that are difficult to reconcile with previous models of planetesimal behavior. The forthcoming Rubin Observatory Legacy Survey of Space and Time (LSST) is poised to further transform our understanding of these classes of objects, and I will discuss the feasibility of future discoveries via ground-based observations as well as possible intercept missions.
