Abstract

The Galactic center is the most active site of star formation in the Milky Way Galaxy, where particularly high-mass stars have formed very recently and are still forming today.The Arches cluster is a young, massive starburst cluster, near the Galactic center.

From wide field JHK imaging we derive the extinction map of the region.

We are analyzing 2 epochs of K band images of the Arches cluster obtained by NACO’s adaptive optics system in order to obtain proper motion membership and derive the density map of the cluster.

In the poster, we will present a first analysis of the distribution of cluster members in the wider area around the cluster core. These data will ultimately allow us to derive the large scale properties of the Arches cluster, such as the total cluster mass, the true extent and the initial mass function.
