Abstract

We construct a generic unified model of sources to account observations of ultra-high energy cosmic rays at & 1019 eV as well as high energy neutrinos above 100 TeV in a framework of photomeson interactions. The mildly efficient in-situ production of & 100 TeV neutrinos with 0.1. t? p. 0.4 must be realized in a source environment to accelerate cosmic rays to ultrahigh energies. The measured fluxes of cosmic rays and neutrinos set the bound on the source luminosity and the emission rate. Tidal disruption events (TDEs) and low-luminosity GRBs are consistent with the present requirements if the Lorentz bulk factor of plasma and the equipartition parameters for cosmic rays and magnetic field are appropriately selected.
