Search for gamma-ray spectral lines from dark matter annihilation with the H.E.S.S. Inner Galaxy Survey
H. E. S. S. Collaboration, F. Aharonian, H. Ashkar +115
Spectral gamma-ray line features are expected as key signatures from dark matter (DM) annihilations of TeV-scale particle DM. Observations of the Galactic Centre with atmospheric C…
Joint X-ray and gamma-ray analysis at the photon level: Application to MSH 15-52
Katharina Egg, Alison M. W. Mitchell
Joint analysis of multi-wavelength (MWL) data at the level of photon events is challenging, but it provides a statistically preferable method of fitting the data, in contrast to fi…
Towards a joint X-ray and gamma-ray analysis of Pulsar Wind Nebulae with Gammapy
Katharina Egg, Alison M. W. Mitchell
The paper describes how the authors adapt eROSITA X-ray data and H.E.S.S. gamma-ray data for joint analysis of pulsar wind nebulae using the Gammapy Python package.
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 remain…
H.E.S.S. observations of composite Seyfert-starburst galaxies
H. E. S. S. Collaboration, A. Acharyya, F. Aharonian +119
Context: Composite galaxies that contain both Seyfert and starburst components may produce very high-energy (VHE; >100 GeV) gamma-ray emission at a wide range of spatial scales, fr…
