Scientific paper

A homogeneous, synchro-self-Compton model (SSC) is used to model the spectra of gamma-ray emitting blazars. The constraints imposed by the rapid variability of the X-rays on a time scale of 1000 s can be met, but require a very large bulk Lorentz factors. These are not consistent with the bulk Lorentz factors implied by observations of apparent super-luminal motion in such sources. A model is also presented in which the target photons for the inverse Compton scattering stem from an external black body source. During a flare, this model predicts a lower relative amplitude of variation in the TeV regime as compared with the X-ray regime. It also gives rise to a steep spectrum in the TeV range. Finally, by varying the electron injection stochastically, the typical patterns of time variation of emission at different wavelengths are presented.
