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…
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…
Particle acceleration signatures in the time-dependent one-zone synchrotron self-Compton model of blazar flares
Paloma Thevenet, Andreas Zech, Catherine Boisson +1
The study of multiwavelength flux and spectral variations during rapid flares from blazars provides strong constraints on the physical parameters of the compact emission regions re…
Hunting Star-Forming Galaxies in the Gamma-Ray Domain
P. Kornecki, J. Biteau, C. Boisson +1
Context. Star-forming galaxies emit γrays with relatively low luminosity, but the study of their emission is no less captivating. While it is known that their γ-ray luminosity in…
Stellar populations from H-band VLT spectroscopy in a sample of seven active galaxies
Isabel Marquez, Catherine Boisson, Monique Joly +2
The relationship between an active galactic nucleus (AGN) and its host galaxy is still far from being understood. Properties of the host galaxies of Seyfert nuclei, such as luminos…
