Constraining the nature of the most extreme Galactic particle accelerator. H.E.S.S. observations of the microquasar V4641 Sgr
A. Acharyya, F. Aharonian, H. Ashkar +131
Microquasars have emerged as promising candidates to explain the cosmic-ray flux at petaelectronvolt energies. LHAASO observations revealed V4641~Sgr as the most extreme example so…
Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory
K. Abe, S. Abe, J. Abhir +491
The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…
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…
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 i…
A Systematic Assessment of Data Volume Reduction for IACTs
Clara Escañuela Nieves, Felix Werner, Jim Hinton
High energy cosmic-rays generate air showers when they enter Earth's atmosphere. Ground-based gamma-ray astronomy is possible using either direct detection of shower particles at m…
