Neutrinos from tidal disruption events

Research output: Contribution to journalConference articlepeer-review

Abstract

When a star is disrupted by a supermassive black hole, and its debris are accreted onto it, a powerful hadronic jet can be generated and be a source of high energy neutrinos and cosmic rays. I review the simplest models of neutrino production from such Tidal Disruption Events (TDEs), and show that the resulting neutrino flux is detectable, and can explain a fraction of the diffuse neutrino flux detected at IceCube. The possibility of a joint explanation of the neutrino and UltraHigh Energy Cosmic Ray data is briefly illustrated. I discuss the hypothesis - which requires further study to be fully substantiated - that a single TDE burst might have been responsible for the 2014-2015 neutrino flare observed by IceCube.
