Explore the relationship between Quasi-Periodic Eruptions (QPEs) and Tidal Disruption Events (TDEs) in this 39-minute conference talk by Riccardo Arcodia from MIT. Delivered at the Kavli Institute for Theoretical Physics' "Anticipating the Rising Tide of Tidal Disruption Events: Theory and Observation" conference, delve into the current understanding of these astrophysical phenomena. Examine how QPEs and TDEs provide insights into galactic nuclei and supermassive black holes, discuss recent advances in wide-field survey capabilities, and consider the theoretical challenges in modeling these events. Investigate the potential of TDEs as tools for deciphering black hole demographics across cosmic time, and explore connections with related fields such as variable Active Galactic Nuclei and X-ray binaries.
