Evidence for a spectral steepening of the gamma-ray emission from the Galactic Center ridge

A. Acharyya, F. Aharonian, H. Ashkar +130

Very-high-energy (VHE) -ray emission detected from the central molecular zone (CMZ) hints at diffusive propagation of cosmic rays (CRs) injected continuously near the Galactic c…

Search for long-term variability of HESS J1745-290

H. E. S. S. Collaboration, :, A. Acharyya +116

At the center of our Galaxy lies the bright γ-ray point-like source HESS J1745-290, which is compatible in position with Sgr A star, although an association between the two remains…

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…

LHAASO J2108+5157 as a Molecular Cloud Illuminated by a Supernova Remnant

A. M. W. Mitchell

The search for Galactic PeVatrons - astrophysical accelerators of cosmic rays to PeV energies - has entered a new phase in recent years with the discovery of the first Ultra-High-E…
