Approximation of the radiation power of electrons due to the inverse-Compton process in the black-body photon field

摘要

Aims. An approximation is presented for the inverse-Compton radiation power of electrons in the isotropic black-body photon field.Methods. This approximation allows calculation of the inverse-Compton emissivity as an integral over the energies of incident electronsrather than over the field photon energies. Such an approach allows for accurate modeling of IC emission of electrons with energy spectra different from power law, in tasks where essential CPU resources are needed.
