High Energy Astronomy from the Ground
نویسنده
چکیده
High Energy Astrophysics (HEA) is a modern interdisciplinary research field at the interface of astronomy, physics and cosmology, with the major objective to study extraterrestrial phenomena in their most energetic and extreme forms. HEA addresses a diversity of observational and theoretical topics related to the nonthermal Universe acceleration, propagation and radiation of relativistic particles in different astronomical environments. Another important topic of HEA is the study of properties of compact relativistic sources as well as cosmological large scale structures through X-radiation of very hot thermal plasmas formed around or inside these objects. Currently, the main research areas that belong to observational HEA are (i) X-Ray Astronomy, (ii) GammaRay Astronomy, (iii) Origin of Cosmic Rays, and (iv) an activity related to the design and construction of large-volume underwater/ice detectors of cosmic high energy neutrinos. This article is devoted to description of the status of the field in the very high energy domain ( 100 E ≥ GeV) covered by measurements with ground-based instruments.

Background Ground-based high energy (HE) astrophysics research today utilises observations with telescopes detecting photons of TeV gamma-ray energies, and particles such as cosmic-rays and neutrinos up to ultra high energies (UHE) above ∼ 10 eV (EeV or Exa,eV). These photons and particles are produced in Nature’s powerhouses such as AGN with supermassive black holes, pulsar and neutron star en...
