Accretion and merger shocks in clusters of galaxies are pote ntial accelerators of high-energy protons, which can give rise to high-energy neutrinos through pp interactions with the intracluster gas. We discuss the possibility that protons from cluster shocks make a significant contribution to the observed cosmic rays in the energy range between the second knee at ∼ 10 eV and the ankle at ∼ 10 eV. The accompanying cumulative neutrino background above ∼PeV may be detectable by upcoming neutrino… CONTINUE READING
