Fig. 1

The arriving energy fluxes following the injection of a 1014 eV photon flux from a source at redshift z = 0.13, with an intervening EGMF = 3 × 10-16 G. Top: the arriving flux is decomposed into that observed from different observer angles, θobs. Bottom: the arriving flux is decomposed into that arriving with different delay times, tdelay. In both plots, the long-short dash line represents the envelope flux containing the non-decomposed spectrum.
