High energy neutrino astronomy Academic Article uri icon


  • The paper discusses the possibilities of carrying out point source neutrino astronomy with detectors of the same type as the very large deep underwater muon and neutrino detector (DUMAND). A flux from a point source of order 100 eV/sq cm-sec in neutrinos more energetic than 300 GeV constitutes a detectable signal for a one-billion-ton detector. The likelihood that supernovae, pulsars, and galactic nuclei produce sufficient high-energy cosmic radiation to produce detectable neutrino fluxes upon interaction with the atmosphere is estimated. Maximum expected counting rates for possible sources are, for a one-billion-ton detector, estimated as follows: expanding supernova remnants - 100 per year; stellar explosions - 0.1-1.0 billion tons per event; pulsars - 1,000 per year; and Seyferts, radio galaxies, and QSOs - 1,000 per year.
