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…
Gamma-ray production in the cosmic-ray -- dark matter scattering as a probe of the axion-like particle -- proton interaction
Victor P. Goncalves, Emmanuel Moulin, Igor Reis +1
The production of very-high-energy (VHE, GeV) gamma rays resulting from the scattering of high-energy cosmic-ray protons off axion-like particles (ALPs) populatin…
The complementary of CTAO, direct detection and collider searches for dark matter in Effective Field Theories and Simplified models
Igor Reis, Andre Scaffidi, Emmanuel Moulin +1
This paper explores the sensitivity of the Cherenkov Telescope Array Observatory to dark matter annihilation in the Galactic Center, within the frameworks of Effective Field Theory…
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…
Probing axion-like particles through the gamma-ray production from cosmic-ray scattering in the Milky Way dark matter halo
Victor P. Goncalves, Emmanuel Moulin, Igor Reis +1
Axion-like particles (ALP) are promising candidates to comprise all the dark matter in the universe. We investigate the ALP couplings to photons and electrons via astrophysical mea…
High-Statistics Measurement of the Cosmic-Ray Electron Spectrum with H.E.S.S
F. Aharonian, F. Ait Benkhali, J. Aschersleben +144
Owing to their rapid cooling rate and hence loss-limited propagation distance, cosmic-ray electrons and positrons (CRe) at very high energies probe local cosmic-ray accelerators an…
H.E.S.S. observations of the 2021 periastron passage of PSR B1259-63/LS 2883
H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +141
PSR B1259-63 is a gamma-ray binary system that hosts a pulsar in an eccentric orbit, with a 3.4 year period, around an O9.5Ve star. At orbital phases close to periastron passages,…
Sensitivity to sub-GeV dark matter from cosmic-ray scattering with very-high-energy gamma-ray observatories
Igor Reis, Emmanuel Moulin, Aion Viana +1
Huge efforts have been deployed to detect dark matter (DM) in the GeV-TeV mass range involving various detection techniques, and led to strong constraints in the available paramete…
Sensitivity to keV-MeV dark matter from cosmic-ray scattering with current and the upcoming ground-based arrays CTA and SWGO
Igor Reis, Emmanuel Moulin, Aion Viana
A wealth of astrophysical and cosmological observational evidence shows that the matter content of the universe is made of about 85 of non-baryonic dark matter. Huge experiment…
Joint H.E.S.S. and Fermi-LAT analysis of the region around PSR J1813-1749
T. Wach, A. M. W. Mitchell, V. Joshi +1
HESS J1813-178 is one of the brightest sources detected during the first HESS Galactic Plane survey. The compact source, also detected by MAGIC, is believed to be a pulsar wind neb…
Modelling of highly extended Gamma-ray emission around the Geminga Pulsar as detected with H.E.S.S
A. M. W. Mitchell, S. Caroff
Geminga is an enigmatic radio-quiet gamma-ray pulsar located at a mere 250 pc distance from Earth. Extended very-high-energy gamma-ray emission around the pulsar has been detected…
