Title: “Modeling the non-thermal emission from blazars”

Abstract:
Blazars are a sub-category of radio-loud active galactic nuclei with relativistic jets pointing towards the observer. They exhibit non-thermal variable emission which practically extends over the whole electromagnetic spectrum. Despite the plethora of multi-wavelength observations, the origin of the emission in blazar jets still remains an open question. We construct a parametric model for studying the connection between the gamma-ray and radio emission of these objects both in steady-state and during flaring. Furthermore, in order to explain the Blazar Sequence and the broader properties of blazars as determined by the Fermi observations, we assume that Accretion Disk MHD Winds provide the necessary ambient photon field for electron scattering and we investigate the role of the mass accretion rate onto the supermassive black hole.
