Potential neutrino signals in a northern hemisphere neutrino telescope from Galactic gamma-ray sources

Abstract

Neutrino energy spectra have been calculated based on the recently measured energy spectra of Galactic very high energy γ-ray sources. Based on these neutrino spectra the expected event rates in the ANTARES neutrino telescope and a future km3 sized neutrino telescope in the Mediterranean Sea, KM3NeT, have been calculated. For the brightest γ-ray sources we find event rates of the order of one neutrino per year in a detector with an instrumented volume of 1 km3. Although the neutrino event rates are comparable to the background from atmospheric neutrinos the detection of individual sources seems possible.
