On the evolution of the particle distribution and the cascade in a moving, expanding emission region in blazar jets
Michael Zacharias
There is a large variety in the models explaining blazar flares. Here, we study the flare profile induced by a moving and expanding blob with special emphasize on the gamma-gamma p…
Gamma-ray observations of MAXI J1820+070 during the 2018 outburst
H. Abe, S. Abe, V. A. Acciari +439
MAXI J1820+070 is a low-mass X-ray binary with a black hole as a compact object. This binary underwent an exceptionally bright X-ray outburst from March to October 2018, showing ev…
Search for dark matter annihilation signals in the H.E.S.S. Inner Galaxy Survey
H. E. S. S. Collaboration, H. Abdalla, F. Aharonian +137
The central region of the Milky Way is one of the foremost locations to look for dark matter (DM) signatures. We report the first results on a search for DM particle annihilation s…
A deep spectromorphological study of the -ray emission surrounding the young massive stellar cluster Westerlund 1
F. Aharonian, H. Ashkar, M. Backes +156
Young massive stellar clusters are extreme environments and potentially provide the means for efficient particle acceleration. Indeed, they are increasingly considered as being res…
Time-resolved hadronic particle acceleration in the recurrent Nova RS Ophiuchi
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +171
Recurrent Novae are repeating thermonuclear explosions in the outer layers of white dwarfs, due to the accretion of fresh material from a binary companion. The shock generated by e…
ExHaLe-jet: An extended hadro-leptonic jet model for blazars. I. Code description and initial results
Michael Zacharias, Anita Reimer, Catherine Boisson +1
The processes operating in blazar jets are still an open question. Modeling the radiation emanating from an extended part of the jet allows one to capture these processes on all sc…
