Line-of-sight cosmogenic neutrino and γ-ray fluxes from TXS 0506+056 (top left) and other blazars (see legend) associated with the IceCube neutrino events. To calculate the cosmogenic fluxes, we assume that UHECRs with energies from 10 PeV to E_p, max escape from the blazars, where the lower range is consistent with the proton energy required to produce neutrinos observed by IceCube via pγ interactions inside the jet. The solid, dashed, and dotted lines corresponds to E_p, max = 1, 10, and 100 EeV. We assume the UHECR luminosity of the associated blazar is L_UHECR = αL_ν, where L_ν is the all-flavor neutrino luminosity inferred from the track-like events observed by IceCube. The filled and open green circles correspond to γ-ray flux data points from Fermi-LAT, and open magenta squares are MAGIC data points. Also shown in the plots are the sensitivities of the current and upcoming γ-ray and neutrino telescopes, as well as the limit on cosmogenic neutrinos by IceCube.
