The study of short-term variability properties in AGN jets has the potential to shed light on their particle acceleration and emission mechanisms. We report results from a four-day…
Radioray response in blazars as a signature of adiabatic blob expansion
Andrea Tramacere, Vitalii Sliusar, Roland Walter +2
Multiwavelength light curves in long-term campaigns have shown that, for several blazars, the radio emission occurs with a significant delay w.r.t. to -ray band, with timescales…
