The IMF and Mass Segregation in Young Galactic Starburst Clusters
The pronounced mass segregation in very young rich Galactic starburst clusters like NGC 3603 and Arches may be due to their extremely short relaxation times and high densities, which appear to lead to rapid dissolution. To what extent mass segregation in these systems is primordial as opposed to evolutionary cannot easily be distinguished. While flat in their centers, the total mass functions of these rich clusters seem close to a Salpeter slope, supporting a universal IMF.
