Description
The diffuse supernova neutrino background (DSNB) is the faint glow of MeV neutrinos from distant core-collapse supernovae. It has not been detected yet, but the Super-K upper limit on the flux of electron antineutrino is very close to modern predictions. Hyper-K is expected to detect dozens of DSNB neutrinos yearly. In addition, Hyper-K will open a new window of neutrinos from core collapses occurring in nearby galaxies. Combined, these provide a tantalizing set of new probes to study the fate of core collapses, the supernova neutrino emission, and the cosmic core-collapse rate.
