Tidal Disruption Events and High-Energy Neutrinos

TL;DR

This paper discusses the connection between Tidal Disruption Events (TDEs) and high-energy neutrinos, highlighting recent observational evidence that supports TDEs as sources of cosmic rays and neutrinos.

Contribution

It presents the first direct observational evidence linking a TDE to a high-energy neutrino, advancing multi-messenger astronomy.

Findings

Identification of TDE AT2109dsg coinciding with neutrino IC191001A

Support for TDEs as sources of cosmic rays and neutrinos

Integration of recent results into broader TDE and neutrino research

Abstract

Tidal Disruption Events (TDEs) occur when stars pass close to supermassive black holes, and have long been predicted to emit cosmic rays and neutrinos. Recently the TDE AT2109dsg was identified in spatial and temporal coincidence with high-energy neutrino IC191001A as part of the Zwicky Transient Facility (ZTF) neutrino follow-up program, providing the first direct observational evidence supporting these objects as multi-messenger sources. In these proceedings, I will place the recent results of our ZTF neutrino follow-up program into the broader context of developments in TDE and neutrino astronomy.
