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…
Search for new cosmic-ray acceleration sites within the 4FGL catalog Galactic plane sources
LAT Collaboration, S. Abdollahi, F. Acero +117
Cosmic rays are mostly composed of protons accelerated to relativistic speeds. When those protons encounter interstellar material, they produce neutral pions which in turn decay in…
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…
Characterization of the GeV emission from the Kepler supernova remnant
Fabio Acero, Marianne Lemoine-Goumard, Jean Ballet
The Kepler supernova remnant (SNR) is the only historic supernova remnant lacking a detection at GeV and TeV energies which probe particle acceleration. A recent analysis of Fermi-…
