Abstract: (arXiv)
We discuss the implication of the observation of supernova relic neutrinos on the study of the star formation rate (SFR) in galaxies. The limit recently obtained at Super-Kamiokande (SK) is already marginally significant: The SFR we derived yrMpc(at a 90% CL) is about twice the SFR estimated from radio observations, and five times the rate from H allowing for uncertainties in the model supernova neutrino flux.- supernova
