dc.description.abstract | A signal of high-energy extraterrestrial neutrinos was discovered by the IceCube experiment [1]. Neutrinos are always produced together with gamma-rays, but the gamma-ray flux from extra- galactic sources cascade down to GeV energies due to attenuation in the intergalactic medium. Hard muon neutrino flux at E > 100 TeV consistent with extragalactic diffuse gamma-ray back- ground measured by Fermi LAT, however soft component of cascade neutrino flux at E < 100 TeV is in conflict with it. Moreover recently a gamma-ray excess at high Galactic latitudes at energies E > 300 GeV in the data of the Fermi telescope was reported [2] . Gamma-ray excess at TeV and neutrino excess at E < 100 TeV can have common galactic origin. In this work we study possibility that both excess in IceCube astrophysical neutrino flux and gamma-ray excess at high galactic latitudes come from interactions of PeV cosmic rays from recent nearby source, like Vela in the walls of Local Bubble. | en_US |
