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 ψ(t0)<0.040M\psi(t_0)<0.040M_{\odot}yr1^{-1}Mpc3^{-3}(at a 90% CL) is about twice the SFR estimated from radio observations, and five times the rate from Hα\alpha allowing for uncertainties in the model supernova neutrino flux.
