Fig. 4


Intrinsic SEDs (unaffected by EBL absorption) of 1 ES 1011+496 (Fig. 3) as inferred by the model, parameters in Table 1. The solid black line shows the hybrid SED with the individual components: proton synchrotron emission (dashed black line) and redistributed synchrotron emission by e±-pairs initiated by photo-hadronic interactions (dash-dotted black line) only observable through pair-cascades. The direct contribution of stable end-products from photo-pion production are negligible in the observable regime peaking above 1027 Hz opaque to γγ-pair-production, see solid brown line (π+ → e+; other processes are below 10-13 erg cm-2 s-1) and only affect the SED indirectly via γγ-pair-production of the nth generation.
