Description

Galactic cosmic rays reach energies of at least several PeV, and their interactions should generate gamma rays and neutrinos from the decay of secondary pions. Therefore, Galactic sources are guaranteed to contribute to the total high-energy cosmic neutrino flux observed by IceCube. We present a search in IceCube data for neutrino emission from Galactic TeV gamma-ray sources detected by the HAWC Gamma Ray Observatory. HAWC serves as an excellent instrument to complement IceCube, with its energy range extending to very high energies. Assuming that the highest energy photons originate from the decay of pions, the very high energy gamma-rays observed by HAWC are expected to be correlated with neutrinos. Using eight years of IceCube data, we report two different analyses to test for this possible neutrino-gamma ray correlation. The first is a stacked analysis of identified HAWC point sources and the second is a template method that accounts for the full morphology of HAWC sources, including extension.
