Abstract: |
The Arches and Quintuplet clusters are valuable probes of the Initial Mass Function (IMF) near the Galactic Center. We use proper motions calculate cluster membership probabilities down to 1-2 M☉, obtaining significantly cleaner samples than is possible through photometry alone. We measure the cluster IMFs while accounting for observational uncertainties, completeness, mass segregation, and stellar multiplicity. We find that the IMFs of both clusters are top-heavy relative to the IMF for local star forming regions. We examine whether these unusual IMFs can be attributed to the Galactic Center environment or are a general property of young massive clusters. |
