New constraints on the origin of medium-energy neutrinos observed by IceCube
The recent IceCube publication claims the observation of cosmic neutrinos with energies down to $\sim 10$ TeV, reinforcing the growing evidence that the neutrino flux in the 10-100 TeV range is unexpectedly large. Any conceivable source of these neutrinos must also produce a $\gamma$-ray flux which degrades in energy en …
