HESS J1303-631 – the mystery TeV source
Is this what is behind the TeV source HESS J1303-631? Some stars, like the Wolf-Rayet star WR124, have enormous stellar winds resulting in shock waves akin to those produced in supernova explosions, and potentially…
TeV gamma rays from the Binary Pulsar PSR B1259-63
Illustration of a binary system similar to the PSR B1259-63/SS 2883 system, where the pulsar orbits a massive Be star with a disk-like outflow of stellar material (from Hubble archive). The actual viewing direction…
The Galactic Center
Radio map of the Galactic Center region (VLA, N.E. Kassim et al.) The Galactic Center region harbors a variety of potential sources of high-energy radiation, such as the supermassive black hole Sgr A* and…
The Active Galaxy PKS 2155-304
Artist’s view of an Active Galactic Nucleus. For Blazar sources such as PKS 2155-304, the relativistic jet emerging from the vicinity of the black hole is directed to the observer and is responsible for…
The Crab Nebula
The Crab Nebula in the optical (FORS Team, VLT, ESO). Since its discovery as a TeV source by the Whipple telescope in 1989, the Crab Nebula serves as a standard candle for TeV astronomy…
