Measuring sizes of marginally resolved young globular clusters with the Hubble space telescope.
CARLSON M.N. and HOLTZMAN J.A.
Abstract (from CDS):
In NGC 3597, we can differentiate between concentrations only for the very brightest clusters; these suggest a concentration of ∼2. Assuming a concentration of 2 for the rest of the objects, we find an average King radius for the clusters in NGC 3597 of 0.7 pc, while the clusters in NGC 1275 have an average radius of 1.1 pc. These are similar to the average core radii for Galactic globular clusters, 0.92 pc. We find average half-light radii of 5.4 and 6.2 pc for the young clusters in NGC 3597 and NGC 1275, respectively, while the average half-light radii of Galactic globular clusters is 3.4 pc. The spread in the derived radial parameters in each cluster system is comparable to that observed in the Galactic globular cluster system.
