Title of the communication: Time-dependent radiative transfer in jets
Preliminary abstract (12 lines max.):
We have developed a computer code which incorporates to various degrees of accuracy the dynamics of a relativistic jet, the evolution of the particle and field components, and the radiative processes thought to be relevant to the high energy emission of blazars. Our main goal is to investigate the spectral evolution during a change of the level of activity. Preliminary results indicate that the inverse Compton light curve has narrower peaks than the synchrotron light curve, although the time of maximum is the same. The flares are best modelled as bursts of energetic particles, uncorrelated or even anticorrelated with the strength of the magnetic field.
