Description

The focus of ground-based gamma-ray astronomy lies in studying the origins of energetic Cosmic Rays (CRs) through the gamma-ray emission produced in the interactions of CRs with their environment. Since the first TeV sources were detected by ground-based instruments around 30 years ago the field has matured considerably, with over 200 Very-High-Energy (VHE, > 1TeV) sources currently known. Just within the last couple of years, considerable progress has been made particularly in the field of transient sources like GRBs and Novae. The successful scientific development of the field is also reflected in the phase transition from closed experiments to the Cherenkov Telescope Array, the first open astronomical observatory in ground-based gamma-ray astronomy, currently under construction.
