Unifying All Blazars

Original · EN

We propose a new physical model for the unification of all Blazars. The blazar phenomenology can be accounted for by a sequence in the source power and intensity of the diffuse radiation field surrounding the relativistic jet. This regulates the equilibrium electron distribution and hence the shape of the spectral energy distribution (SED), and in turn the classification into a blazar "flavour". The processes inside and beside the emitting jet are the same throughout the blazar class. Objects along this sequence would be observationally classified as High-frequency-peaked BL Lac objects (HBL), Low-frequency BL Lac objects (LBL), Highly Polarized Quasars (HPQ) and Lowly Polarized Quasars (LPQ).
