Calculation of UHE Neutrino Luminosity of SN1987A and UHE Gamma-Ray Flux from Underground Experiment

Abstract

SN1987A can be a very strong UHE gamma-ray and UHE neutrino source. If one UHE neutrino event is observed at Kamioka per month, the UHE neutrino luminosity is calculated ∼3.6 ×10⁴¹ erg/sec and UHE gamma-ray (E_γ ≥10¹⁴ eV) flux ∼2.2 ×10^-10 cm^-2sec^-1, assuming a spectrum ∼F₀E^α and α= 2.
