Sensitivity of the IceCube-Gen2 Neutrino Telescope for SN Neutrinos
While optimized for detecting neutrinos in the multi-GeV and TeV region, IceCube is also capable of detecting the large flux of MeV neutrinos from Galactic Core Collapse Supernovae that stream through the detector. This is achieved by analyzing the collective enhancement of the PMT rate on top of a...
