Abstract

Very-high-energy(VHE,E≥100 GeV)γ-ray observation is an important part of the all-panchromatic astronomy and is a window used to investigate cosmic rays.As VHE γ-ray photons carry important physical information,study of these particles can greatly enhance our knowledge of cosmological evolution,generating mechanisms/environments/source-region geometry of high-energy cosmic-ray particles,as well as the interactions between high-energy particles or those between such particles and intergalactic medium.Imaging Atmospheric Cherenkov Telescopes(IACTs)have large effective collecting areas,wide fields of view(FoV),low-energy thresholds and high angular resolutions.These telescopes have become important tools of the VHE γ-rays astronomy.More than 90 VHE γ-rays sources have been detected by IACTs,some of which have been identified as Active Galactic Nuclei(AGN),Wolf-Rayet stars,Giant Molecular Clouds(GMCs),shell-type Supernova Remnants(SNRs),Pulsar Wind Nebulae(PWNe),and binary-star systems.In this paper,we review instruments and methods of data analysis of ground-based VHE γ-ray observation.
