Abstract
While existing neutrino detectors would see a burst of many events from a supernova in the Milky Way, the expected supernova rate is only a few per century. As an alternative, we propose the detection of ~ 1 neutrino per supernova from galaxies within 10 Mpc, in which there were at least 9 core-collapse supernovae since 2002. This is a possibly faster method for collecting enough events to study the supernova neutrino spectrum, which is essential for calibrating numerical models and predicting the redshifted spectrum from very distant supernovae. It would also allow a > 10^4 times more precise trigger time than optical data alone for high-energy neutrinos and gravitational waves.
