Web site of Supernova Relic Neutrino Background
--- on the basis of the metallicity evolution of galaxies ---

Abstract

This web site provides models of supernova relic neutrino (SRN) flux from past stellar collapses including black hole formation (failed supernovae). On the basis of the metallicity evolution of galaxies, the dependences of SRNs on the cosmic star formation rate density, shock revival time and equation of state are considered. We show the results for the reference model and models with maximum and minimum values of SRN event rate among models investigated. For the details, see Nakazato et al., Astrophys. J. 804 (2015) 75, arXiv:1503.01236 [astro-ph.HE]. For the neutrino spectra emitted from various progenitors, we utilize the Supernova Neutrino Database; Nakazato et al., Astrophys. J. Supp. 205 (2013) 2, arXiv:1210.6841 [astro-ph.HE]. This data set is open for general use in any research for astronomy, astrophysics, and physics, provided that our papers are referenced in your publication.
