Image for: First discovery of gamma-ray emission from the direction of a globular cluster


Fig. 1. The globular cluster Terzan 5 (centre) in visible light and the gamma-ray source HESS J1747 – 248. The gamma-ray intensity is displayed in false colours from blue (low) to white (high). The smaller circle (solid) comprises half of the mass of Terzan 5. A zoom on this central region in infrared light is depicted in the upper right inset. The larger circle (dashed) shows to what extension stars are gravitationally bound to the cluster.
