Galactic sources: update information from gamma-rays experiments and implications for IceCube |
|
Résumé |
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. 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. We show that observing them over the
twenty-year lifetime of the instrumentation is likely, and that some
should be observable at the 3 sigma level with six years of data. In
the absence of positive results, we derive constraints on the spectral
index and cut-off energy of the sources, assuming a hadronic
acceleration mechanism. |
