Supernova neutrino burst

WebTwenty years ago, the neutrino burst from supernova (SN) 1987A in the Large Magellanic Cloud was observed. On 23 February 1987 at 7:35 h universal time, the Kamiokande II [1, 2] and IMB [3, 4] water-Cherenkov detectors each registered a burst clearly attributed to SN 1987A. A contemporaneous signal in the Baksan scintillator detector [5, 6] may have … Web7 set 2024 · A core-collapse supernova releases the vast majority of the gravitational binding energy of its compact remnant in the form of neutrinos over an interval of a few tens of seconds. In the event of a core-collapse supernova within our galaxy, multiple current and future neutrino detectors would see a large burst in activity.
