The H.E.S.S. Cherenkov telescopes

The international H.E.S.S. (High Energy Stereoscopic System) experiment consists of an array of five Cherenkov telescopes operating in Namibia since 2004, with the fifth telescope operational since 2012. H.E.S.S. is the only array of its kind in the southern hemisphere. It provides unprecedented access to the sky at very high energies, above around 100 GeV. The observations made by the H.E.S.S. consortium have led to numerous results, including the discovery of new categories of TeV sources in our galaxy and beyond, supernova remnants, pulsar wind nebulae, star clusters, X-ray binaries, diffuse emission from at PeVatron at the galactic centre, radio galaxies, blazars, gamma-ray bursts, a starburst galaxy...

All these discoveries are advancing our understanding of very high-energy physical phenomena, particle acceleration mechanisms and the origin of cosmic rays.
The LUX team is particularly involved in the observation, analysis and modelling of active galactic nuclei.
