BILAND, ADRIAN 2012 <jats:p> Very High Energy Gamma-Ray Astronomy (the measurement of γ above 10 GeV) is a rather young but fast evolving field. In the past 16 years some 20 sources have been discovered, about half of them are firmly established and seen with high significance by more than one experiment. This rather short list already contains very different objects like plerions, supernova remnants and active galactic nuclei. A new generation of instruments (CANGAROO III, HESS, MAGIC, VERITAS) is just starting to take data, and first preliminary results show that the sensitivity is improved by at least a factor of 100. Already during commissioning, some new sources have been discovered. </jats:p><jats:p> This overview will summarize the techniques used in VHE gamma-ray observations as well discuss briefly some physics topics that can be investigated in this energy range. </jats:p> https://sonar.ch/global/documents/283734 eng info:eu-repo/semantics/altIdentifier/doi/10.1142/s0217751x05030661 info:eu-repo/semantics/altIdentifier/issn/0217-751X International Journal of Modern Physics A. - World Scientific Pub Co Pte Lt. - 2005, vol. 20, no. 29, p. 6981-6990 Nuclear and High Energy Physics Astronomy and Astrophysics Atomic and Molecular Physics, and Optics GROUND-BASED GAMMA-RAY ASTRONOMY http://purl.org/coar/resource_type/c_6501
