The radio morphology of a spatially resolved SSC model

Abstract

One of the main, unresolved questions about the nature of quasars is the position of the acceleration site responsible for the highest energies. The attempt to investigate this question in the energy regime with the highest resolution, the radio band, has the downside that no theoretical model exists that can connect these two regimes. The model in this work tries to shrink this gap by extending the general synchrotron self Compton (SSC) model up to length scales in the order of the resolution of radio observations. The resulting spectral energy distributions (SED) show a qualitative improvement in the representation of the radio spectrum. Furthermore the obtained emission morphology shows similar properties to the radio structures observed in jets of quasars. A complete and quantitative connection will however need either much higher numerical effort or an improved methodology.
