Title: AN ANGLE-DEPENDENT SYNCHROTRON SELF-COMPTON MODEL FOR RELATIVISTIC JET SOURCES

Abstract

We report on the development of a numerical code to calculate the angle-dependent synchrotron + synchrotron self-Compton radiation from relativistic jet sources with partially ordered magnetic fields and anisotropic particle distributions. Using a multi-zone radiation transfer approach, we can simulate magnetic-field configurations ranging from perfectly ordered (unidirectional) to randomly oriented (tangled). We demonstrate that synchrotron self-Compton model fits to the spectral energy distributions (SEDs) of extragalactic jet sources may be possible with a wide range of magnetic-field values, depending on their orientation with respect to the jet axis and the observer. This is illustrated with the example of a spectral fit to the SED of Mrk 421 from multiwavelength observations in 2006, where acceptable fits are possible with magnetic-field values varying within a range of an order of magnitude for different degrees of B-field alignment and orientation.
