universe. If a supernova appears at the center of our Galaxy, 10,000
events are detected by Superkamiokande, and it is expected fruitful
information on the supernova core and neutrino physics are obtained.
After reviewing the recent simulations of stellar core collapse, we show
how the neutrino burst time profile and spectra are modified by neutrino
oscillation. We also show the spectra of relic neutrinos emitted by past
supernovae, and discuss the possibility of the detection of this
neutrino background.
