Upper panel: the contribution to the EGB from AGN winds predicted by our SAM is compared to the contribution provided by the blazar population (Ajello et al. 2015). Model predictions are shown for our fiducial model and for different accelerated proton spectral index: p = 2 (dotted blue lines), p = 2.2 (solid blue lines), and p = 2.4 (dashed blue lines). The red shaded region represent the sum of the AGN wind and blazar contributions to the EGB. The data points are as in Fig. 4. Lower panel: fraction of EGB provided by AGN winds and blazars.
