The Electron Spectrum in 3C 279 and the Observed Emission Spectrum [PDF]

open access: yesThe Astrophysical Journal, 2003
The emission mechanisms of the blazar 3C 279 are studied by solving the kinetic equations of electrons and photons in a relativistically moving blob. The gamma-ray spectral energy distribution (SED) is fitted by inverse Compton scattering of external photons.
