摘要：
In this paper the current status of gamma-ray observations of starburst galaxies from hundreds of MeV up to TeV energies with space-based instruments and ground-based Imaging Atmospheric Cherenkov Telescopes (IACTs) is summarised. The properties of the high-energy (HE; 100 MeV <= E <= 100 GeV) and very-high-energy (VHE; E >= 100GeV) emission of the archetypical starburst galaxies M 82 and NGC 253 are discussed and put into context with the HE gamma-ray emission detected from other galaxies that show enhanced star-formation activity such as NGC 4945 and NGC 1068. Finally, prospects to study the star-formation - gamma-ray emission connection from Galactic systems to entire galaxies with the forthcoming Cherenkov Telescope Array (CTA) are outlined.
