Multi-messenger Observations of Tidal Disruption Events

Abstract

Using the Zwicky Transient Facility (ZTF) and other observatories, we have identified three candidate Tidal Disruption Events (TDEs) in spatial and temporal coincidence with high-energy neutrinos detected by IceCube: AT2019dsg, AT2019fdr and AT2019aalc. All three of these events have been shown to be able to produce high-energy neutrinos. In these proceedings, I will give an overview of Tidal Disruption Events, outline our follow-up program with ZTF, describe the observations carried out for each of those coincident events and highlight their similarities and differences.
