Supernova Model Discrimination with Hyper-Kamiokande

Core-collapse supernovae are among the most magnificent events in observable universe. They produce many of chemical elements necessary for life to exist and their remnants -- neutron stars black holes interesting astrophysical objects own right. However, despite millennia observations almost a century study, explosion mechanism core-collapse is not yet well understood. Hyper-Kamiokande next-generation neutrino detector that will be able observe flux from next galactic supernova unprecedented detail. We focus on first 500 ms burst, corresponding accretion phase, use newly-developed, high-precision event generator simulate Hyper-Kamiokande's response five different models. show distinguish between these models with high accuracy at distance up 100 kpc. Once happens, this ability powerful tool guiding simulations towards precise reproduction observed nature.
