High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S
F. Aharonian, F. Ait Benkhali, J. Aschersleben +144
Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators an…
Very-high-energy -ray emission from young massive star clusters in the Large Magellanic Cloud
F. Aharonian, F. Ait Benkhali, J. Aschersleben +129
The Tarantula Nebula in the Large Magellanic Cloud is known for its high star formation activity. At its center lies the young massive star cluster R136, providing a significant am…
Separating source-intrinsic and Lorentz invariance violation induced delays in the very high energy emission of blazar flares
C. Levy, H. Sol, J. Bolmont
Aims: The aim of the present study is to explore how to disentangle energy-dependent time delays due to a possible Lorentz invariance violation (LIV) at Planck scale from intrinsic…
Dark Matter Line Searches with the Cherenkov Telescope Array
S. Abe, J. Abhir, A. Abhishek +562
Monochromatic gamma-ray signals constitute a potential smoking gun signature for annihilating or decaying dark matter particles that could relatively easily be distinguished from a…
Curvature in the very-high energy gamma-ray spectrum of M87
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +132
The radio galaxy M87 is a variable very-high energy (VHE) gamma-ray source, exhibiting three major flares reported in 2005, 2008, and 2010. Despite extensive studies, the origin of…
Acceleration and transport of relativistic electrons in the jets of the microquasar SS 433
F. Aharonian, F. Ait Benkhali, J. Aschersleben +161
SS 433 is a microquasar, a stellar binary system with collimated relativistic jets. We observed SS 433 in gamma rays using the High Energy Stereoscopic System (H.E.S.S.), finding a…
