Exciting Prospects for Detecting Late-Time Neutrinos from Core-Collapse Supernovae

The importance of detecting neutrinos from a Milky Way core-collapse supernova is well known. An under-studied phase is proto-neutron star cooling. With the high statistics expected for present and near-future detectors, it should be possible to obtain detailed neutrino signals from before the start of the cooling phase to very late times. We present the first comprehensive study of late-time signal detection, considering a variety of outcomes, using all flavors, and employing detailed detector physics. Our results show that these data would allow unprecedented probes of the properties of the proto-neutron star, including the onset of neutrino transparency and hence the transition to a neutron star. If a black hole forms, even at very late times, this can be clearly identified.
