Search for Time-Dependent Neutrino Emission from Selected X-ray Binary Sources

ORAL

Abstract

Binaries are systems of compact objects, black holes or neutron stars, that have a companion star gravitationally bound to them. They are observed in X-ray and some in gamma rays up to TeV energies. In such systems, cosmic rays may be accelerated in stellar winds or jets, resulting in the production of neutrinos. IceCube, which is a neutrino detector located in the South Pole, detects astrophysical neutrinos with energies in 100 Tev. We are searching for neutrinos from 6 selected binaries by correlating 13 years of IceCube data with electromagnetic light curves. The electromagnetic light curves being used are X-ray Soft and Hard, and Gamma which are taken from SWIFT, MAXI, and Fermi. The method consists of constructing temporal pdf for each source using the light curves and looking for transient emission at the location of the source.
