Speaker
Description
The Super-Kamiokande (SK) experiment has now the potential of detecting yet-unobserved neutrinos coming from different astronomical sources after the gadolinium loading of the water in July, 2020. The improvement in identification of neutrons emitted from inverse beta decay reactions enhances therefore SK’s sensitivity to low energy electron anti-neutrinos. Pre-supernova stars, which are massive stars in the last stage of nuclear fusion before their core collapses, emit high fluxes of electron anti-neutrinos from thermal processes. The pre-supernova neutrinos from the silicon burning phase can be emitted over a few days before the core collapse, and their detection can provide early warnings for core collapses and subsequent supernovae. We report the sensitivity of Super-Kamiokande to these "pre-supernova" neutrinos and details of the alert system based on their detection, which has been running in SK since October, 2021.
