(For the H.E.S.S. Collaboration)
Globular clusters (GCs) are large collections of old stars that are orbiting the core of a galaxy. Our Milky Way Galaxy has about 160 known GCs, with perhaps more to be discovered. We analysed 20 GCs observed by the H.E.S.S. very-high-energy (>100 GeV) gamma-ray telescopes. The detection of Terzan 5 was confirmed and flux upper limits were obtained for the remaining 19 sources. We accumulated the necessary parameters for each GC and ran a numerical model that predicts the inverse Compton gamma-ray flux expected from each cluster. The five most promising GCs for future observations by Cherenkov Telescope Array (CTA) will be highlighted.
