We present the results from four years detection of the IceCube neutrino observatory of high energy astrophysical neutrinos. The search for such neutrinos and their sources is an extremely important part for the search of very powerful astrophysical objects where cosmic rays are accelerated to very high energy. We compare the directions from which these high energy neutrino arrive with the directions of gamma-ray and hard X-ray sources.
