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…
H.E.S.S. detection of the PSR J0855-4644 nebula
F. Aharonian, H. Ashkar, M. Backes +131
HESS J0852-463 is a TeV γ-ray source located in the Galactic plane. The region consists of a supernova remnant (SNR, RX J0852.0-4622) with a shell-like morphology, commonly referre…
High Energy Emission from the Galactic Center
Andrea Goldwurm, Maïca Clavel, Stefano Gabici +1
The center of the Galaxy is a prominent source in X-rays and gamma-rays. The study of its high-energy (HE) emission is crucial in understanding the physical phenomena taking place…
Constraining the nature of the most extreme Galactic particle accelerator. H.E.S.S. observations of the microquasar V4641 Sgr
A. Acharyya, F. Aharonian, H. Ashkar +131
Microquasars have emerged as promising candidates to explain the cosmic-ray flux at petaelectronvolt energies. LHAASO observations revealed V4641~Sgr as the most extreme example so…
Energy-dependent gamma-ray morphology estimation tool in Gammapy
K. Feijen, R. Terrier, B. Khélifi +4
An understanding of the energy dependence of gamma-ray sources can yield important information on the underlying emission mechanisms. However, despite the detection of energy-depen…
On the cosmic-ray distribution in the Galactic Center region: New insights from H.E.S.S
J. Devin, A. Lemière, K. Streil +2
We performed a spectro-morphological analysis of the diffuse emission in the Galactic center region with H.E.S.S. gamma-ray data. We relied on templates to model the diffuse emissi…
