| Abstract : | Blazars are well known for their continuous non-thermal electromagnetic radiation and aperiodic flux variability across the entire electromagnetic spectrum. The variability is observed over a wide range of time scales varying from few minutes to several years. However, the physical processes operating in the blazar jet are still an open question. There is a long debate on the possible origin of the high energy emission whether it is leptonic, or hadronic. In this presentation, an estimation of the various time scales involved in the feasible hadronic and leptonic interactions in blazar jet and their influence on the typical variability time scales will be discussed. |
