Dr. Nataly Ospina – INFN Bari Monitoring Supernova Neutrinos with Super-Kamiokande

Core-Collapse Supernovae are among the most powerful events in the Universe, where neutrinos play a key role by carrying away about 99% of the released energy. These neutrinos are emitted minutes to hours before the electromagnetic signal, providing a powerful early warning for astronomical observations. Super-Kamiokande, a large water Cherenkov detector in Japan, continuously monitors its data in real time to identify supernova neutrino bursts and issue rapid alerts.

In this seminar, I will present recent upgrades to the Super-Kamiokande supernova monitoring and alert system, including the methods to estimate the distance and direction of a supernova using neutrino data. I will also talk about how these alerts are used to coordinate rapid follow-up observations with telescope networks, helping us to observe the supernova at the earliest stages.
