Results from an IceCube Search for High-Energy Neutrino Emission from X-ray Binaries

ORAL

Abstract

X-ray binaries are one of the long-standing candidates as the source of Galactic cosmic rays and neutrinos. The compact object in a binary system can be the site for cosmic-ray acceleration, while interactions of cosmic rays can happen in the jet of the compact object, the wind, or the companion star’s atmosphere, which produce high-energy neutrinos. I will talk about a comprehensive study of TeV-scale neutrinos from high-mass and low-mass X-ray binaries conducted by IceCube using muon data. In the absence of significant correlation, we place upper limits on the neutrino fluxes from these sources and provide a comparison with theoretical predictions. Finally, I will present the detectability of X-ray binaries in IceCube-Gen2.
