Scientific paper

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.
