The Diffuse Interstellar Emission from Radio to Gamma Rays

Current observations of our Galaxy from radio to gamma rays show that diffuse emission is mostly concentrated in the plane and in the inner Galaxy, but it also largely extends in all-sky directions. Most of the diffuse emission is produced by Galactic cosmic rays interacting with interstellar photons, dust/gas, and magnetic fields. We describe our effort on modeling such an emission and we give updates based on publicly available data from NASA missions.
