High energy gamma-ray astronomy has recently made significant progresss through ground-based instruments like the H.E.S.S. array of imaging atmospheric Cherenkov telescopes. The unprecedented angular resolution and the large field of view has allowed to spatially resolve for the first time the morphology of gamma-ray sources in the TeV energy range. The experimental technique is described and the types of sources detected and still expected are discussed. Selected results include objects as… 
Extragalactic sources of rapidly variable high energy gamma radiation
Extragalactic sources of high-energy cosmic gamma-rays, like blazars and quasars, are usually highly variable and the temporal characteristics of their light curves are key to the understanding of


A low level of extragalactic background light as revealed by γ-rays from blazars
The diffuse extragalactic background light consists of the sum of the starlight emitted by galaxies through the history of the Universe, and it could also have an important contribution from the
Dependence of the gamma-ray emission from SN 1006 on the astronomical parameters
We use nonlinear kinetic theory to study the remnant dynamics and the particle acceleration as well as the properties of the nonthermal emission from the supernova remnant SN 1006. The known range of
Discovery of the Binary Pulsar PSR B1259-63 in Very-High-Energy Gamma Rays around Periastron with H.E.S.S
The discovery of very-high-energy (VHE) γ-ray emission of the binary system PSR B1259−63/SS 2883 of a radio pulsar orbiting a massive, luminous Be star in a highly eccentric orbit provides unambiguous evidence for particle acceleration to multi-TeV energies in thebinary system.
