Ultra-high energy cosmic rays (UHECRs) accelerated in the jets of active galactic nuclei can accumulate in high magnetic field, ∼ 100 kpc-scale regions surrounding powerful radio galaxies. Photohadronic processes make ultra-relativistic electrons and positrons that initiate electromagnetic cascades, leading to the production of a γ-ray synchrotron halo. We calculate the halo emission in the cas...

The relevant γ energy range is explicitly identified where additional γ strength has to be located for having an impact on astrophysically relevant reactions. It is shown that folding the energy dependences of the transmission coefficients and the level density leads to maximal contributions for γ energies of 2 ≤ Eγ ≤ 4 unless quantum selection rules allow isolated states to contribute. Under t...
