Abstract:
IceCube neutrino telescope recently discovered astrophysical neutrinos in the energy range from 10 TeV to 10 PeV. This discovery challenged existed theoretical models due to unexpected observation of soft 1/E^{2.5} neutrino spectrum for cascade data and at the same time $1/E^{2.1}$ spectrum for muon neutrinos. Together with limits from diffuse gamma-ray flux measured with Fermi LAT this excluded most of existed theoretical predictions. In my talk I'll review theoretical models, which can explain observed data both with Galactic and extra-galactic sources of neutrinos.
