Expanding shells of young pulsars as sources of high-energy neutrinos

The initial power outputs P sub 0 of pulsars are not well known, but these seem to approximately follow a distribution law N(greater than P sub 0) proportional to P sub 0 to the -n power, where n is in the range 0.5-1.0. It seems likely that P sub 0 is not less than 10 to the 38th ergs/sec. With these assumptions, it is estimated that the DUMAND detector can record more than 1000 high-energy (exceeding 4 TeV) neutrino events in a four-month period per Galactic supernova. Neutrinos from supernova shells in the Virgo supercluster would be marginally detectable if N(greater than P sub 0) proportional to P sub 0 to the -0.5 power, but undetectable is proportional to P sub 0 to the -1 power. The diffuse flux summed over distant extragalactic supernovae is likely to be well below the detection threshold
