TeV gamma-ray astronomy
Abstract:Covering a broad energy range from ~100 GeV to 100 TeV and above, celestial TeV gamma rays are accessed by telescopes based on the ground, unlike x-rays and lower energy gamma rays, which can only be detected using instruments in space. The natural advantage this gives such telescopes in terms of collection area is now being exploited by a generation of instruments with unprecedented sensitivity and angular resolution, and these are revealing a Universe rich in new phenomena. This paper briefly describes the techniques and telescopes currently in operation, reviews some highlights so far, provides a catalogue of sources as of May 2007 and looks at some likely future observatories and experiments.
