A Glimpse of the Sky at TeV Energies
摘要
Some fundamental concepts for the TeV energy astrophysics, together with gamma-ray non-thermal production mechanisms are presented in this chapter. After a short description on the processes that are accelerating cosmic rays in the Universe, the production mechanisms for gamma rays are presented. Some of the experiments and observatories dedicated to the detection of very-high-energy gamma rays are outlined with the related detection technique are briefly depicted. The main astrophysical sources emitting at GeV/TeV energies in the Galactic Center region are presented.
