Figure 1: The extragalactic diffuse high-energy background shown as a plot of E2 times photon number spectrum versus energy using the compilation of Ajello et al. [6]. Two components are apparent, each described by a broken power law, showing two maxima in emitted energy around 25 keV and 20 MeV. The solid line indicates the sum of both fitted components. The new Fermi LAT data points are at the highest energies, indicated in red.
