Abstract
The temporal structure of low-energy (20-60 MeV) neutrino interactions within the IMB-3 detector during 863 days of livetime between 1986 Ma y and 1991 March has been analyzed. The neutrino data are consistent w ith expected cosmic-ray-induced neutrino interactions with no bursts e vident (excluding SN 1987A). When combined with the 327 effective live days of IMB-1 data, we place a 90% C.L. upper limit of less-than-or-eq ual-to 0.71 Galactic supernovae yr-1. We have also performed a tempora l correlation analysis with gamma-ray bursts (GRBs) using a subset of the low-energy neutrino data. No significant correlations were observe d for coincidence windows of 1 minute, 1 hour, or 1 day.
