High-Energy Neutrino Sources in the Infra-Red

Astrophysical neutrino sources were first discovered by IceCube in 2013, and there has since been an ongoing search to find the origin of these neutrinos. Neutrino detections are now published in real-time in the form of public alerts, enabling electromagnetic follow-up. In recent years, neutrino follow-up campaigns by the Zwicky Transient Facility (ZTF) at optical wavelengths have identified two Tidal Disruption Events (TDEs) as likely neutrino sources. These TDEs both exhibited dramatic dust echoes, as seen in observations at NIR and MIR wavelengths. Searching for similar dust echoes revealed a third TDE-like flare as another likely neutrino source. I will discuss how IR can be used to identify further neutrino sources, and the prospects for a planned IR neutrino follow-up program with the upcoming WINTER telescope
