Talk Title: "Looking for the origin of astrophysical neutrinos"


IceCube neutrino telescope recently discovered astrophysical neutrinos in the energy range from 10 TeV to 3 PeV. This discovery challenged existed theoretical models due to unexpected observation of soft 1/E^{2.5} neutrino spectrum. 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. I'll present model, which at the same time explain Ultra-High Energy Cosmic Ray protons, astrophysical neutrinos and diffuse gamma-ray background.
