“…One method to further probe neutrino emission from TDEs is via direct neutrino correlation searches. Beyond IceCube, one such search with the ANTARES Neutrino Telescope did not find any evidence of excess TeV-PeV neutrino emission from AT2019dsg, though the corresponding neutrino flux predictions outlined above lay below the sensitivity of the ANTARES analysis [63,64]. The Baikal-GVD neutrino telescope reported preliminary indications of a possible neutrino excess from AT2019dsg, but analysis of this source is still ongoing [65].…”

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.

“…For TeV XRBs, in a recent ANTARES time-integrated point-source search (Illuminati 2021), HESS J0632+057 has a pre-trial p-value 0.02 while this periodic analysis finds a pre-trial p-value 9.0 × 10 −3 , the second most significant in the analysis. However, the flare search gives a pre-trial p-value of 1 while it is not included in the time-integrated search.…”

We present the first comprehensive search for high-energy neutrino emission from high-and lowmass X-ray binaries conducted by IceCube. Galactic X-ray binaries are long-standing candidates for the source of Galactic hadronic cosmic rays and neutrinos. The compact object in these systems can be the site of cosmic-ray acceleration, and neutrinos can be produced by interactions of cosmic rays with radiation or gas, in the jet of a microquasar, in the stellar wind, or in the atmosphere of the companion star. We study X-ray binaries using 7.5 years of IceCube data with three separate analyses. In the first, we search for periodic neutrino emission from 55 binaries in the Northern Sky with known orbital periods. In the second, the X-ray light curves of 102 binaries across the entire sky are used as templates to search for time-dependent neutrino emission. Finally, we search for time-integrated emission of neutrinos for a list of 4 notable binaries identified as microquasars. In the absence of a significant excess, we place upper limits on the neutrino flux for each hypothesis and compare our results with theoretical predictions for several binaries. In addition, we evaluate the sensitivity of the next generation neutrino telescope at the South Pole, IceCube-Gen2, and demonstrate its power to identify potential neutrino emission from these binary sources in the Galaxy.
