THE STAR CLUSTER POPULATION OF THE COLLISIONAL RING GALAXY NGC 922
THE STAR CLUSTER POPULATION OF THE COLLISIONAL RING GALAXY NGC 922
We present a detailed study of the star cluster population detected in the galaxy NGC 922, one of the closest collisional ring galaxies known to date, using Hubble Space Telescope/Wide Field Planetary Camera 2 UBVI photometry, population synthesis models, and N-body/smoothed particle hydrodynamics simulations. We find that 69% of the …
