Description
Super-Kamiokande (SK) is known as the most sensitive detector to the supernova neutrinos originating in our galaxy.
SK also has a sensitivity to neutrinos from the extra-galactic supernova within 10 Mpc from Earth, called a “mini-burst”, which is expected to occur once every few years. Recently, SN2023ixf, one of the mini-bursts, is recognized as the closest supernova in the last few years. Mini-bursts like SN2023ixf have been reported in worldwide telescopes in past decades. Therefore, we searched supernova neutrinos from the mini-burst from the time when SK started (1996) to the present (2024).
This poster shows the search results of the “mini-burst neutrino” search and their detection probability, including extra-galactic regions, in SK.
