Abstract
IceCube has observed a flux of cosmic neutrinos, with a "bump" in the energy range 10 less than or similar to E/TeV less than or similar to 100 that creates a 3 sigma tension with gamma-ray data from the Fermi satellite. This has been interpreted as evidence for a population of hidden cosmic-ray accelerators. We propose an alternative explanation of this conundrum on the basis of cold dark matter which decays into sterile neutrinos after oscillations produce the bump in the cosmic neutrino spectrum.
