Discovery of VHE emission from PKS 0447-439 with H.E.S.S. and MWL studies
A. Zech, B. Behera, Y. Becherini +13
Very-high energy (VHE) emission has been detected from PKS 0447-439 with the H.E.S.S. Cherenkov telescope array. This blazar is one of the brightest hard-spectrum extragalactic obj…
Search for Lorentz Invariance breaking with a likelihood fit of the PKS 2155-304 flare data taken on MJD 53944
HESS Collaboration, A. Abramowski, F. Acero +193
Several models of Quantum Gravity predict Lorentz Symmetry breaking at energy scales approaching the Planck scale (10^{19} GeV). With present photon data from the observations of d…
H.E.S.S. constraints on Dark Matter annihilations towards the Sculptor and Carina Dwarf Galaxies
HESS Collaboration, A. Abramowski, F. Acero +192
The Sculptor and Carina Dwarf spheroidal galaxies were observed with the H.E.S.S. Cherenkov telescope array between January 2008 and December 2009. The data sets consist of a total…
New unidentified H.E.S.S. Galactic sources
O. Tibolla, R. C. G. Chaves, O. de Jager +4
H.E.S.S. is one of the most sensitive instruments in the very high energy (VHE; > 100 GeV) gamma-ray domain and has revealed many new sources along the Galactic Plane. After the su…
Unidentified Gamma-Ray Sources as Ancient Pulsar Wind Nebulae
O. C. de Jager, S. E. S. Ferreira, A. Djannati-Ataï +6
In this paper we explore the evolution of a PWN while the pulsar is spinning down. An MHD approach is used to simulate the evolution of a composite remnant. Particular attention is…
