| Abstract: |
Analysis of the temporal evolution of particle populations and of radiation tranfer along relativistic jets allows us to generate light curves of blazars at different frequencies. In our modelling, stationary emission from radio to X-rays is due to the synchrotron radiation of relativistic electrons ejected from the central engine in an inhomogeneous VLBI jet. Variability and flares are due to evolving synchrotron and Inverse-Compton radiation of additional compact components (blob or shock) travelling along the jet. We consider two scenarios for the highly energetic particles of compact components, which are either injected from the central engine, or accelerated in situ. The model can explain connection between variability observed from the radio to the X-rays frequencies, and predicts also possible correlation with very high energy gamma ray flares. New data obtained for Mrk421 in 2001 show a flare in the radio range (at 2.7 and 5 GHz) correlated with a X-ray flare observed by RXTE. We show how the acceleration scenario well describes the temporal evolution of such multispectral flare. |
