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 (…
Possible Evidence for Cosmic-Ray Acceleration in the Type Ia SNR RCW 86: Spatial Correlation between TeV Gamma rays and Interstellar Atomic Protons
H. Sano, G. Rowell, E. M. Reynoso +13
We present a detailed morphological study of TeV gamma rays, synchrotron radiation, and interstellar gas in the young Type Ia supernova remnant (SNR) RCW 86. We find that the inter…
H.E.S.S. discovery of very high energy gamma-ray emission from PKS 0625-354
H. E. S. S. Collaboration, H. Abdalla, A. Abramowski +253
PKS 0625-354 (z=0.055) was observed with the four H.E.S.S. telescopes in 2012 during 5.5 hours. The source was detected above an energy threshold of 200 GeV at a significance level…
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…
