Prospects for Detecting Galactic Sources of Cosmic Neutrinos with IceCube: An Update

Understand

Air-Cherenkov telescopes have mapped the Galactic plane at TeV energies.

• Here we evaluate the prospects for detecting the neutrino emission from sources in the Galactic plane assuming that the highest energy photons originate from the decay of pions, which yields a straightforward prediction for the neutrino flux from the decay of the associated production of charged pions.
• Four promising sources are identified based on having a large flux and a flat spectrum.
• We subsequently evaluate the probability of their identification above the atmospheric neutrino background in IceCube data as a function of time.
