Modelling blazar flaring using a time-dependent fluid jet emission model - an explanation for orphan flares and radio lags

Abstract:

Blazar jets are renowned for their rapid violent variability and multiwavelength flares, however, the physical processes responsible for these flares are not well understood. In this paper we develop a time-dependent inhomogeneous fluid jet emission model for blazars. We model optically thick radio flares for the first time and show that they are delayed with respect to the prompt optically thin emission by ∼ months to decades, with a lag that increases with the jet power and observed wavelen...
