, 2015 Context. Blazars are astrophysical sources whose emission is dominated by non-thermal processes, i.e. synchrotron and inverse Compton emission. Although the general picture is rather robust and consistent with observations, many aspects are still ...TAGLIAFERRI, GIANMARIA, F. Tavecchio, Bonnoli, G, Giarrusso, M, Sandrinelli, A., E.
