Tiivistelmä
Blazars are active galactic nuclei which emit powerful plasma jets close to our line of sight. The plasma emits radiation via synchrotron and inverse Compton processes. In inverse Compton models, it is generally assumed that the high energy emission is produced via external Compton where the radiation sources external-to-jet, such as accretion disk or broad line clouds provide the soft photons for inverse Compton scattering. Synchrotron self-Compton models generally underproduce the gamma-ray flux levels generally observed in bright sources.We report the implications of nonlinear cooling in synchrotron self-Compton models and suggest that the such a model can reproduce the entire spectral energy distribution of blazars self-consistently. Our results imply that the synchrotron self-Compton cooling may turn nonlinear in powerful gamma-ray sources, especially during the high energy flares.
