Description

Core-collapse supernovae bursts are among the most energetic transients known in the universe. PandaX-4T, a dual-phase xenon dark matter experiment, has the ability to capture coherent elastic neutrino-nucleus scatterings signals. In this study, the total neutrino events is estimated to be from 6.6 to 13.7 at 10 kpc over 10-second duration with negligible backgrounds, depending on supernova progenitors of different masses. Two specialized triggering alarms, golden and silver, for monitoring supernova burst neutrinos are built, at false alert rates of one per month and one per week, respectively. There are a 100% probability of detecting SN explosions in our galaxy out to 10 kpc. This algorithm will soon be used in the real-time supernova monitor system to provide the astronomy community with supernova early warnings.
