The contribution to the EGB from AGN winds (blue) and starburst galaxies (red) predicted by our SAM. Fiducial model parameters are set at: h_d = 100 pc, η_p = 0.1, ϵ_AGN = 0.01, and ϵ_SN = 0.1. Accelerated proton spectral index equal to p = 2.2 is assumed for both AGN winds and starburst galaxies. The blue and red shaded bands represent the uncertainty related to the EBL model adopted (Stecker et al. 2016). The data points are the Fermi-LAT measurement of the EGB, with black and grey vertical error bars indicating EGB statistical and systematic uncertainties, respectively (Ackermann et al. 2015).
