1. Introduction: Young star clusters 2. Integral Field Spectroscopy: Determine accurate stellar radial velocities with MUSE 3. The gas and stellar radial velocity profile of the Galactic young star cluster Westerlund 2 4. Summary
Peter Zeidler Young star clusters: the Galactic nursery
Stars are typically formed in clustered environments
Cluster formation channels: • Monolithic (centrally condensed burst-like) cluster formation • Hierarchical cluster formation via subsequent merging

Westerlund 2 Young star clusters (≤ 5 Myr) have not had time to evolve and are close to their initial conditions
