Gamma-ray bounds from EAS detectors and heavy decaying dark matter constraints
Gamma-ray bounds from EAS detectors and heavy decaying dark matter constraints
The very high energy Galactic $\gamma$-ray sky is partially opaque in the ($0.1-10$) PeV energy range. In the light of the recently detected high energy neutrino flux by IceCube, a comparable very high energy $\gamma$-ray flux is expected in any scenario with a sizable Galactic contribution to the neutrino flux. …
