Yuhan Yao is an Assistant Professor at the Kavli Institute for Astronomy and Astrophysics, Peking University. With a broad interest in time domain astronomy and high energy astrophysics, she uses wide-field sky surveys and targeted multi-wavelength observations to study the physics of energetic transients, such as the disruption of stars by massive black holes and the explosions of stars. Before joining Peking University in 2026, Yuhan was a Miller Postdoctoral Fellow at the University of California, Berkeley, obtained her Ph.D. from Caltech in 2023 , and received her B.S. in Astronomy from Peking University in 2018.Tidal disruption events (TDEs) illuminate otherwise dormant massive black holes, offering a window into their demographics and the physics of stellar disruption. In this talk, I will explore two emerging directions. First, I will present off-nuclear TDEs as probes of wandering black holes, a population naturally predicted by galaxy assembly but for which direct observational evidence remains scarce. I will discuss recent discoveries, their properties and volumetric rates, and their implications for the abundance and origins of wandering black holes, including intermediate-mass black holes. Second, I will turn to TDEs associated with black holes weighing >~1e+8 Msun, where disruptions occur close to the direct-capture boundary and relativistic effects may strongly influence the outcome. Drawing on recent results and ongoing work, I will discuss their distinctive emission and outflow properties and the questions they raise about this regime, which remains largely unexplored by numerical simulations.
