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…

Gamma-Ray Constraints on Heavy Axion-Like-Particle Decays from Fermi-LAT and H.E.S.S. Blazar Spectra

A. Acharyya, F. Aharonian, M. Backes +117

The propagation of very-high-energy (VHE; GeV) gamma rays from extragalactic sources is affected by interactions with photons of the extragalactic background light (…

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…

Enhancing event reconstruction for -ray particle detector arrays using transformers

Markus Pirke, Youngwan Son, Jonas Glombitza +3

Gamma-ray astronomy from hundreds of GeV to PeV is confined to ground-based experiments that detect air showers induced by -rays entering Earth's atmosphere. While particle dete…

Application of Graph Networks to a wide-field Water-Cherenkov-based Gamma-Ray Observatory

Jonas Glombitza, Martin Schneider, Franziska Leitl +2

With their wide field of view and high duty cycle, water-Cherenkov-based observatories are integral to studying the very high-energy gamma-ray sky. For gamma-ray observations, prec…

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…
