Description

The detection of neutrinos from SN1987A ushered in a new era in astrophysics, proving their value as a key tool for studying stellar evolution and supernova mechanisms. The neutrinos from core-collapse supernova bursts can be detected by coherent elastic neutrino-nucleus scatterings in dark matter direct detection experiments with tonne-scale liquid xenon. We have developed an online supernova monitoring system which integrates a GPS module of millisecond-level time precision at PandaX-4T. The monitoring system has a low false alert rate and is sensitive to core-collapse supernova explosions in the Milky Way. The technique can also be applied to the following PandaX-20T experiment.
