Recently IceCube collaboration discovered astrophysical neutrinos  of unknown origin.

 Our group  developed methods to study  both galactic and extragalactic contributions to to this signal.

Goal of this stage is to develop  model of astrophysical neutrino sources, which consistent both with neutrino and 

gamma-ray data and make predictions for  contributions of various classes of astrophysical sources

in future data of IceCube and km3 experiments
