H.E.S.S. observations of the globular clusters NGC 6388 and M 15 and search for a Dark Matter signal

Understand

Observations of the globular clusters NGC 6388 and M 15 were carried out by the H.E.S.S.

• array of Cherenkov telescopes for a live time of 27.2 and 15.2 hours respectively.
• No gamma-ray signal is found at the nominal target position of NGC 6388 and M 15.
• In the primordial formation scenario, globular clusters are formed in a dark matter halo and dark matter could still be present in the baryon-dominated environment of globular clusters.
