Abstract

The next core-collapse supernova in our Galaxy will be a spectacular event, with some 10410^4 neutrino detections in total expected among several detectors. This data will allow unprecedented tests of neutrino properties and new opportunities in astrophysics. In this paper, I focus on two main topics: (1) Measurement of the νμ\nu_\mu and ντ\nu_\tau masses by time-of-flight, with an emphasis on introducing as little supernova model dependence as possible, and (2) Methods for locating a supernova by its neutrinos in advance of the light, which may allow improved astronomical observations. In the latter, I also discuss the recent result that the positrons from νˉe+pe++n\bar{\nu}_e + p \to e^+ + n are not isotropically emitted, as commonly thought.
