For electrons with energies Ee >∼ 1 GeV, the primary energy-loss processes during prop- agation are synchrotron radiation in magnetic fields and ICS with background photons

Common framework The electron propagation in the ISM is typically described by the diffusion-loss equation, written as: ∂N ∂t = ∇ · (D∇N) + ∂(bN) ∂Ee + Q , (1) where Ee is the elec
