Particle Transport within the Pulsar Wind Nebula HESS J1825-137
H. E. S. S. Collaboration, H. Abdalla, F. Aharonian +225
Aims: We present a detailed view of the pulsar wind nebula (PWN) HESS J1825-137. We aim to constrain the mechanisms dominating the particle transport within the nebula, accounting…
VHE -ray discovery and multi-wavelength study of the blazar 1ES 2322-409
H. E. S. S. Collaboration, :, H. Abdalla +232
A hotspot at a position compatible with the BL Lac object 1ES 2322-409 was serendipitously detected with H.E.S.S. during observations performed in 2004 and 2006 on the blazar PKS 2…
Searches for gamma-ray lines and `pure WIMP' spectra from Dark Matter annihilations in dwarf galaxies with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +234
Dwarf spheroidal galaxies are among the most promising targets for detecting signals of Dark Matter (DM) annihilations. The H.E.S.S. experiment has observed five of these systems f…
First Ground-based Measurement of Sub-20 GeV to 100 GeV -rays from the Vela Pulsar with H.E.S.S. II
H. E. S. S. Collaboration, H. Abdalla, F. Aharonian +230
We report on the measurement and investigation of pulsed high-energy -ray emission from the Vela pulsar, PSR B083345, based on 40.3 hours of observations with the largest tel…
The -ray spectrum of the core of Centaurus A as observed with H.E.S.S. and Fermi-LAT
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +249
Centaurus A (Cen A) is the nearest radio galaxy discovered as a very-high-energy (VHE; 100 GeV-100 TeV) -ray source by the High Energy Stereoscopic System (H.E.S.S.). It is a fa…
The starburst galaxy NGC 253 revisited by H.E.S.S. and Fermi-LAT
H. E. S. S. Collaboration, H. Abdalla, F. Aharonian +231
(Abridged) Context. NGC 253 is one of only two starburst galaxies found to emit -rays from hundreds of MeV to multi-TeV energies. Accurate measurements of the very-high-energy (…
Population study of Galactic supernova remnants at very high -ray energies with H.E.S.S.
H. E. S. S. Collaboration, :, H. Abdalla +252
Shell-type supernova remnants (SNRs) are considered prime candidates for the acceleration of Galactic cosmic rays (CRs) up to the knee of the CR spectrum at $\mathrm{E} \approx \ma…
Detection of variable VHE gamma-ray emission from the extra-galactic gamma-ray binary LMC P3
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +253
Context. Recently, the high-energy (HE, 0.1-100 GeV) -ray emission from the object LMC P3 in the Large Magellanic Cloud (LMC) has been discovered to be modulated with a 10.3-day…
A search for new supernova remnant shells in the Galactic plane with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +263
A search for new supernova remnants (SNRs) has been conducted using TeV gamma-ray data from the H.E.S.S. Galactic plane survey. As an identification criterion, shell morphologies t…
