CTA: The Future of Very-High-Energy Gamma-Ray Astrophysics |
|
Abstract |
The Cherenkov Telescope Array (CTA) will be the next generation gamma-ray observatory with the aim of investigating the very high-energy emission from a large variety of astrophysical sources in the energy range from 20 GeV to 300 TeV. The full array, comprising 118 telescopes of 3 sizes, will be installed in two sites, one in the northern and one in the southern hemisphere, in order to provide whole-sky coverage with a significant improvement in sensitivity compared to the current major arrays such as H.E.S.S., MAGIC and VERITAS. Beyond deeper investigation of already known classes of sources, CTA will make possible the quest of new classes of TeV sources, such as GRBs or cluster of galaxies. With an improved angular resolution and in conjunction with pushing the high-energy limit beyond the hundreds of TeV, CTA will allow a very deep exploration of the cut-off regime in cosmic rays acceleration processes. Concerning the dark matter field, the search for annihilation signature in the Galactic halo and in dwarf spheroidal galaxies is part of the key science for CTA. The status of the CTA project, with particular emphasis to the approaching LST inauguration, will be presented, overviewing the technological implications for achieving the science goals described above. |
