Candidate Tidal Disruption Event AT2019fdr Coincident with a High-Energy Neutrino

Understand

The origins of the high-energy cosmic neutrino flux remain largely unknown.

• Recently, one high-energy neutrino was associated with a tidal disruption event (TDE).
• Here we present AT2019fdr, an exceptionally luminous TDE candidate, coincident with another high-energy neutrino.
• Our observations, including a bright dust echo and soft late-time X-ray emission, further support a TDE origin of this flare.
