Figure 1: The extragalactic diffuse high-energy background shown as a plot of $E^2$ 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 $25\text{keV}$ and $20\text{MeV}$. The solid line indicates the sum of both fitted components. The new Fermi LAT data points are at the highest energies, indicated in red.
