Multi-messenger Observations of Tidal Disruption Events

TL;DR

This paper reports multi-messenger observations linking three Tidal Disruption Events with high-energy neutrinos, providing insights into their potential as neutrino sources and detailing follow-up observations.

Contribution

It presents the first identification of TDEs coinciding with high-energy neutrinos using ZTF and IceCube data, demonstrating their capability to produce neutrinos.

Findings

Three TDEs are spatially and temporally coincident with neutrino detections.

All three TDEs can produce high-energy neutrinos.

The paper details follow-up observations and comparisons of these 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.
