Models of the cosmic-ray, γ-ray and synchrotron properties of the Galaxy allow conclusions to be drawn about the cosmic-ray injection spectrum and propagation parameters. While the simplest models fail to reproduce the data, reasonable extensions can explain a range of observational facts. Explanations for the diffuse γ-ray GeV excess found by EGRET are considered; inverse-Compton emission resulting from a hard electron injection spectrum appears most promising. Meanwhile the γ-ray emission at MeV energies is unlikely to originate entirely from cosmic-ray electrons, and a point source component is required in addition.
