Search for High-Energy Neutrinos from Tidal Disruption Events (TDEs) — •Robert Stein for the IceCube collaboration — DESY Zeuthen, Germany

Since the detection of high-energy cosmic neutrinos at the IceCube Neutrino Observatory in 2013, there has been an on-going search to find suitable transient source candidates. So far, Supernovae, Blazars and GRBs are all currently disfavoured as dominant contributors to the observed neutrino flux. However, Tidal Disruption Events (TDEs) represent a promising untested source class. Various models have predicted neutrino emission from jetted, or even from non-jetted TDEs. I will present an analysis framework to test correlations between TDEs and high-energy neutrinos from several years of IceCube data. The analysis will be a time-dependent stacking analysis, incorporating TDEs overlapping the data-taking period, to improve sensitivity. Preliminary sensitivity estimates for the analysis will be shown.
