Abstract
Using the Glashow resonance candidate event recently identified by IceCube, we infer the ultra-high energy astrophysical neutrino source. Since it can distinguish νe from νe, the Glashow resonance is a valuable probe to identify the source of astrophysical neutrinos. With the available experimental information we set a constraint on the νe fraction of astrophysical neutrinos and find that the μ-damped pγ source is excluded at about 2σ confidence level and that there is a weak preference for the pp source. Next generation neutrino telescopes will be able to distinguish between ideal pp and pγ sources with a high significance assuming a single power-law neutrino spectrum.
