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…
The extreme HBL behaviour of Markarian 501 during 2012
M. L. Ahnen, S. Ansoldi, L. A. Antonelli +276
A multiwavelength campaign was organized to take place between March and July of 2012. Excellent temporal coverage was obtained with more than 25 instruments, including the MAGIC,…
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 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 (…
