    • Characterising the long-term variability of blazars in leptonic models 

      Thiersen, Hannes; Zacharias, Michael; Böttcher, Markus (MDPI, 2019)
      Most research on blazar variability focuses on individual flares to explain acceleration and radiation mechanisms and improve on current models. These short-time events (being minutes, hours, or days) might not be ...
    • The long-lasting activity in the flat spectrum radio quasar (FSRQ) CTA 102 

      Zacharias, Michael; Böttcher, Markus; Jankowsky, Felix; Lenain, Jean-Philippe; Wagner, Stefan J. (MDPI, 2019)
      The flat spectrum radio quasar CTA 102 ( z=1.032 ) went through a tremendous phase of variability. Since early 2016 the gamma-ray flux level has been significantly higher than in previous years. It was topped by a four ...
