Detection of a neutrino signal from SN 1987A on February 23, 1987 at 7:35 UT: Data from the Baksan Underground Scintillation Telescope

Context. 1987A-like events form a rare sub-group of hydrogen-rich core-collapse supernovae that are thought to originate from the explosion of blue supergiant stars. Although SN 1987A is the best known supernova, very few objects of this group have been discovered and, hence, studied. Aims. In this paper we investigate the properties of SN 2009E, which exploded in a relatively nearby spiral galaxy (NGC 4141) and that is probably the faintest 1987A-like supernova discovered so far. We also attempt to characterize this subgroup of core-collapse supernovae with the help of the literature and present new data for a few additional objects.

“…The core-collapse supernovae (CCSNe) explosion mechanism is driven by low energy (MeV) neutrinos, which are responsible for releasing most of the gravitational binding energy of the system. These neutrinos were observed for the first time in 1987 by Kamiokande-II (Hirata et al 1987), Irvine-Michigan-Brookhaven detector (Bionta et al 1987), and Baksan (Alexeyev & Alexeyeva 2008), where 24 candidate neutrino events were observed between the three detectors. In addition to MeV neutrinos, some CCSNe are good candidates for the production of high-energy (HE) neutrinos GeV and higher due to dense circumstellar material (CSM), which provides target material for the ejecta to form shocks and accelerate protons with matter via hadronuclear (pp interaction) or photohadronic (pγ) mechanism.…”

Large neutrino detectors like IceCube monitor for core-collapse supernovae using low energy (MeV) neutrinos, with a reach to a supernova neutrino burst to the Magellanic Cloud. However, some models predict the emission of high energy neutrinos (GeV-TeV) from core-collapse supernovae through the interaction of ejecta with circumstellar material and (TeV-PeV) through choked jets. In this paper, we explore the detection horizon of IceCube for core-collapse supernovae using high-energy neutrinos from these models. We examine the potential of two high-energy neutrino data samples from IceCube, one that performs best in the northern sky and one that has better sensitivity in the southern sky. We demonstrate that by using high-energy neutrinos from core-collapse supernovae, the detection reach can be extended to the Mpc range, far beyond what is accessible through low-energy neutrinos. Looking ahead to IceCube-Gen2, this reach will be extended considerably.

Large neutrino detectors like IceCube monitor for core-collapse supernovae using low-energy (MeV) neutrinos with a detection reach from a supernova neutrino burst to the Magellanic Cloud. However, some models predict the emission of high-energy neutrinos of GeV–TeV from core-collapse supernovae through the interaction of ejecta with circumstellar material with energies of TeV–PeV produced through choked jets. In this paper, we explore the detection horizon of IceCube for core-collapse supernovae using high-energy neutrinos from these models. We examine the potential of two high-energy neutrino data samples from IceCube, one that performs best in the northern sky and one that has better sensitivity in the southern sky. We demonstrate that, by using high-energy neutrinos from core-collapse supernovae, the detection reach can be extended to the megaparsec range, far beyond what is accessible through low-energy neutrinos. Looking ahead to IceCube-Gen2, this reach will be extended considerably.
