Searching the Sources of Mysterious Particles from the Universe

H.E.S.S., the "High Energy Stereoscopic System", is designed to search the electromagnetic spectrum of the sky in the Southern Hemisphere for the sources of extremely high energy particles and enables fundamental research in the fields of astronomy and astrophysics. H.E.S.S. is a collaboration between many European and African institutions.

The H.E.S.S. telescope system was realized in close cooperation with the University of Namibia. It supports the international cooperation in fundamental research as well as the education of young scientists and technicians in southern Africa. The project was initiated by the Max Planck Institute for Nuclear Physics in Heidelberg. Major components of the telescopes and the infrastructure were provided by the Max-Planck-Gesellschaft and the Max Planck Institute for Nuclear Physics in close collaboration with research groups from the universities of Hamburg and Bochum, the Humboldt-University of Berlin and from the Landessternwarte Heidelberg, with support from the Federal German Ministry für Education and Research (Bundesministerium für Bildung und Forschung (BMBF)) within the funding framework "Astroteilchenphysik". Important technical contributions came from the French collaboration partners. The other international partners from Europe and southern Africa provided valuable additional contributions to the project.

The new research instrument consists in its first phase of a cluster of 4 optical telescopes, which are coupled to a system and which can be extended in a later stage. The experiment is designed to operate initially for about 10 to 15 years. Namibian companies, like NEC and Seelenbinder Consulting Engineers, have realized the technical infrastructure in close cooperation to the highest technical level.

First observations with H.E.S.S. have been performed during the stepwise commissioning of the individual telescopes in 2002 and 2003. From these measurements important results have already been obtained and which marked scientific highlights at conferences on astroparticle physics in 2004. Among these results is the discovery of a source of high-energy gamma rays at the center of our Galaxy, which is probably a remnant of a supernova that exploded about 10,000 years ago.

The inauguration of H.E.S.S. takes place on Tuesday, September 28, 2004 at 10.30 am local time at the location of H.E.S.S. on the Farm Goellschau in Namibia.
