dc.description.abstractHigh energy particles interacting with the extragalactic photon background initiate electromagnetic pair cascades. I discuss here the resulting constraints on UHECR models, the flux of cosmogenic neutrinos and the extragalactic magnetic field (EGMF). In the former case, the diffuse isotropic gamma radiation measured by Fermi-LAT is used to show that cosmogenic neutrino fluxes are only marginally detectable by existing and currently planned neutrino experiments. In the latter case, the non-observation of 1ES 0229+200 by Fermi-LAT requires that the EGMF is stronger in at least 60% of space than ~ 5×10−15G (stationary source) or ~ 10−17G (flaring source). Thus the (non-) observation of GeV extensions around TeV blazars probes the EGMF in voids and puts strong constraints on the origin of EGMFs, favoring a primordial origin.nb_NO
