SUMMARY:Looking for the origin of astrophysical neutrinos\, NPAC (Nucl
 ear/Particle/Astro/Cosmo) Forum\, Dmitri Semikoz\, APC Paris
DESCRIPTION:IceCube neutrino telescope  recently discovered astrophysi
 cal neutrinos  in the  energy range from 10 TeV to 3 PeV. This discove
 ry challenged existed theoretical models due to unexpected observation
  of soft  1/E^{2.5}  neutrino spectrum. Together with limits from diff
 use gamma-ray flux measured with Fermi LAT this excluded most of exist
 ed theoretical predictions. In my talk I'll discuss significance of th
 e galactic component observation in the 4 years IceCube data. Also I'l
 l review theoretical models\, which can explain observed data both wit
 h Galactic and extra-galactic sources of neutrinos.  Finally\, I'll pr
 esent model\, which at the same time explain Ultra-High Energy Cosmic 
 Ray protons\, astrophysical neutrinos and diffuse gamma-ray background
