  2. Supernova neutrinos - Wikipedia

    en.wikipedia.org/wiki/Supernova_Neutrinos

    Wilson's delayed neutrino explosion mechanism has been used for 30 years to explain core collapse supernova. [1] Evolutionary stages of the core-collapse supernova: [15] (a) Neutronization phase (b) In-fall of material and neutrino trapping (c) Generation of shock wave and neutrinos burst (d) Stalling of shock wave (e) Neutrino heating (f ...

  4. Neutrino - Wikipedia

    en.wikipedia.org/wiki/Neutrino

    A neutrino (/ nj uː ˈ t r iː n oʊ / new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity. [2] [3] The neutrino is so named because it is electrically neutral and because its rest mass is so small that it was long thought to be zero.

    Using an observatory under construction deep beneath the Mediterranean Sea near Sicily, scientists have detected a ghostly subatomic particle called a neutrino boasting record-breaking energy in ...

  6. SuperNova Early Warning System - Wikipedia

    en.wikipedia.org/wiki/Supernova_Early_Warning_System

    The SuperNova Early Warning System (SNEWS) is a network of neutrino detectors designed to give early warning to astronomers in the event of a supernova in the Milky Way, our home galaxy, or in a nearby galaxy such as the Large Magellanic Cloud or the Canis Major Dwarf Galaxy. As of March 2021, [1] SNEWS has not issued any supernova alerts.

  7. Helium and Lead Observatory - Wikipedia

    en.wikipedia.org/wiki/Helium_And_Lead_Observatory

    It was designed to be a low-cost, low-maintenance detector [5] with limited capabilities [6]: 38 sufficient for the burst of neutrinos generated by a nearby supernova. Its major components are left over from other decommissioned experiments: 76 tons of lead from an earlier cosmic-ray experiment, and 128 three-metre-long helium-3 neutron ...
