    • The exceptional VHE gamma-ray outburst of PKS 1510-089 in May 2016 

      Zacharias, Michael; Sitarek, Julian; Prester, Dijana Dominis; Jankowsky, Felix; Lindfors, Elina (PoS, 2017)
      PKS 1510-089 (z=0.361) is one of only a handful of flat spectrum radio quasars that have been detected at very high energy (VHE, E > 100GeV) gamma rays. It is a very active source across the entire electromagnetic spectrum. ...
    • The extended jet in AP Librae as the source of the VHE γ-ray emission 

      Zacharias, Michael; Wagner, Stefan J. (AIP, 2017)
      Most modeling attempts of blazars use a small emission zone located close to the central black hole in order to explain the broad-band spectral energy distribution. Here we present a case where additionally to the small ...
    • The FSRQ PKS 1510-089: the gamma-ray-synchrotron connection 

      Jankowsky, Felix; Zacharias, Michael; Wagner, Stefan J.; Kurtanidze, Omar (PoS, 2017)
      The flat spectrum radio quasar (FSRQ) PKS 1510-089 (z=0.361) is known for its complex multiwavelength behaviour. Since 2015, it has been very active across the entire electromagnetic spectrum. This has lead to joint ...
    • Implications of time-dependent injection in relativistic jets 

      Zacharias, Michael (AIP, 2017)
      Rapid blazar flaring events and their rich behavior require time-dependent modeling. One important approach is time-dependent injection causing non-linear cooling effects, since the inevitable SSC cooling depends on the ...
    • Monitoring of the FSRQ PKS 1510-089 with H.E.S.S. 

      Zacharias, Michael; Jankowsky, Felix; Mohamed, Mahmoud; Prokoph, Heike; Sanchez, David (PoS, 2017)
      The flat spectrum radio quasar (FSRQ) PKS 1510-089 (z=0.361) is known for its complex multiwavelength behavior. It has been monitored regularly at very high energy (VHE, E > 100GeV) gamma-rays with H.E.S.S. since its ...
    • Multi-wavelength observations of flaring blazars with ATOM and Fermi-LAT 

      Jankowsky, Felix; Böttcher, Markus; Zacharias, Michael; Wagner, Stefan J.; Kurtanidze, Omar (Sissa Medialab, 2017)
      The Automatic Telescope for Optical Monitoring is a 75cm optical telescope located at the H.E.S.S. site in Namibia. Since 2005, it monitors around 250 gamma-ray emitting AGN and has observed numerous blazar flares in several ...
