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…

Ultra-High-Energy Gamma-Ray Bubble around Microquasar V4641 Sgr

R. Alfaro, C. Alvarez, J. C. Arteaga-Velázquez +89

Microquasars are laboratories for the study of jets of relativistic particles produced by accretion onto a spinning black hole. Microquasars are near enough to allow detailed imagi…

A new method of reconstructing images of gamma-ray telescopes applied to the LST-1 of CTAO

CTA-LST Project, :, K. Abe +305

Imaging atmospheric Cherenkov telescopes (IACTs) are used to observe very high-energy photons from the ground. Gamma rays are indirectly detected through the Cherenkov light emitte…

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…

TeV Analysis of a Source Rich Region with HAWC Observatory: Is HESS J1809-193 a Potential Hadronic PeVatron?

A. Albert, R. Alfaro, C. Alvarez +79

HESS J1809-193 is an unidentified TeV source, first detected by the High Energy Stereoscopic System (H.E.S.S.) Collaboration. The emission originates in a source-rich region that i…

H.E.S.S. observations of the 2021 periastron passage of PSR B1259-63/LS 2883

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +141

PSR B1259-63 is a gamma-ray binary system that hosts a pulsar in an eccentric orbit, with a 3.4 year period, around an O9.5Ve star. At orbital phases close to periastron passages,…

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…
