Supernova neutrino burst as a probe of shock waves and matter density fluctuations
Future detection of a supernova neutrino burst by large underground detectors would give important information about the supernova matter density profile and unknown neutrino properties, due to the effects of flavor oscillations in the supernova envelope. We mainly discuss the detectability of signatures associated to the shock-wave propagation in observable neutrino signals. We also investigate the effects of possible small-scale stochastic matter density fluctuations in the wake of supernova shock waves. We find that such fluctuations can partly erase the shockwave imprint on the neutrino event spectra.
