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…

Prompt Searches for Very-High-Energy γ-Ray Counterparts to IceCube Astrophysical Neutrino Alerts

J. Abhir, A. Biland, K. Brand +817

The search for sources of high-energy astrophysical neutrinos can be significantly advanced through a multi-messenger approach, which seeks to detect the gamma rays that accompany…

Combined dark matter search towards dwarf spheroidal galaxies with Fermi-LAT, HAWC, H.E.S.S., MAGIC, and VERITAS

LAT Collaboration, S. Abdollahi, L. Baldini +586

Dwarf spheroidal galaxies (dSphs) are excellent targets for indirect dark matter (DM) searches using gamma-ray telescopes because they are thought to have high DM content and a low…

H.E.S.S. programme searching for VHE gamma rays associated with FRBs

F. Aharonian, A. Archaryya, J. Aschersleben +127

Fast Radio Bursts (FRBs) are highly energetic, extremely short-lived bursts of radio flashes. Despite extensive research, the exact cause of these outbursts remains speculative. Th…

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…

Detection of very-high-energy gamma-ray emission from Eta Carinae during its 2020 periastron passage

H. E. S. S. Collaboration, F. Aharonian, F. Ait Benkhali +137

The colliding-wind binary system Carinae has been identified as a source of high-energy (HE, below 100\,GeV) and very-high-energy (VHE, above 100\,GeV) gamma rays…
