Synchrotron and inverse-Compton emission from blazar jets – I. A uniform conical jet model.
POTTER W.J. and COTTER G.
Abstract (from CDS):
In the model we evolve the electron population dynamically along the jet taking into account the synchrotron and inverse-Compton losses. The inverse-Compton emission is calculated using the Klein-Nishina cross-section and a relativistic transformation into the jet frame, and we explicitly show the seed photon population. We integrate synchrotron opacity along the line of sight through the jet plasma, taking into account the emission and opacity of each section of the jet. In agreement with previous studies of radio emission, we find that a conical jet model which conserves magnetic energy produces the characteristic blazar flat radio spectrum; however, we do not require any fine-tuning of the model to achieve this. Of particular note, in our model fit to BL Lac - which at ∼ 1037 W is a relatively low jet-power source - we find no requirement for significant re-acceleration within the jet to explain the observed spectrum.
