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…

The second H.E.S.S. gamma-ray burst catalogue: 15 years of observations with the H.E.S.S. telescopes

A. Acharyya, F. Aharonian, C. Arcaro +143

Recent observational efforts using imaging atmospheric Cherenkov telescopes (IACTs) have led to firm detections of very-high-energy (VHE) signals from bright gamma-ray bursts (GRBs…

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…

HESS J1831098 -- Exploring a pulsar halo scenario with H.E.S.S. data

Karim Sabri, Yves Gallant, Justine Devin +1

Pulsar halos are a class of extended very-high-energy (VHE) sources highlighted by the HAWC observatory towards the Geminga pulsar and PSR B065614. These VHE sources are interpr…

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…

The H.E.S.S. extragalactic sky survey with the first decade of observations

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +140

The results of the first extragalactic gamma-ray survey by the High Energy Stereoscopic System (H.E.S.S.) are presented. The survey comprises 2720 hours of very high-energy gamma-r…
