Acceleration of petaelectronvolt protons in the Galactic Centre
Galactic cosmic rays reach energies of at least a few petaelectronvolts (of the order of 1015 electronvolts). This implies that our Galaxy contains petaelectronvolt accelerators (‘PeVatrons’), butExpand
Search for Dark Matter Annihilations towards the Inner Galactic Halo from 10 Years of Observations with H.E.S.S.
The inner region of the Milky Way halo harbors a large amount of dark matter (DM). Given its proximity, it is one of the most promising targets to look for DM. We report on a search for theExpand
Search for photon-linelike signatures from dark matter annihilations with H.E.S.S.
Gamma-ray line signatures can be expected in the very-high-energy (E(γ)>100 GeV) domain due to self-annihilation or decay of dark matter (DM) particles in space. Such a signal would be readilyExpand
The 2012 flare of PG 1553+113 seen with H.E.S.S. and Fermi-LAT
Very high energy (VHE, E > 100 GeV)gamma-ray flaring activity of the high-frequency peaked BL Lac object PG 1553 + 113 has been detected by the H.E.S.S. telescopes. The flux of the source increasedExpand
Science with the Cherenkov Telescope Array
The Cherenkov Telescope Array, CTA, will be the major global observatory for very high energy gamma-ray astronomy over the next decade and beyond. The scientific potential of CTA is extremely broad:Expand
Search for dark matter annihilation signatures in H.E.S.S. observations of Dwarf Spheroidal Galaxies
Dwarf spheroidal galaxies of the Local Group are close satellites of the Milky Way characterized by a large mass-to-light ratio and are not expected to be the site of nonthermal high-energy gamma-rayExpand
HESS J1640−465 – an exceptionally luminous TeV γ-ray supernova remnant
The results of follow-up observations of the TeV gamma-ray source HESS J1640-465 from 2004 to 2011 with the High Energy Stereoscopic System (HESS) are reported in this work. The spectrum is wellExpand
Discovery of the Hard Spectrum VHE γ-Ray Source HESS J1641–463
This Letter reports the discovery of a remarkably hard spectrum source, HESS J1641-463, by the High Energy Stereoscopic System (H.E.S.S.) in the very high energy (VHE) domain. HESS J1641-463 remainedExpand
Probing the extent of the non-thermal emission from the Vela X region at TeV energies with H.E.S.S.
Vela X is a region of extended radio emission in the western part of the Vela constellation: one of the nearest pulsar wind nebulae (PWNe), and associated with the energetic Vela pulsar (PSRExpand
Constraints on axionlike particles with H.E.S.S. from the irregularity of the PKS 2155−304 energy spectrum
Axionlike particles (ALPs) are hypothetical light (sub-eV) bosons predicted in some extensions of the Standard Model of particle physics. In astrophysical environments comprising high-energy gammaExpand
