Star cluster complexes.

Young star clusters clustered themselves in regions. There interactions, mergers and disruptions may occur.Here we propose to measure the kinematics of these regions.

-Important stage in the star clusters life.

-Stars may be released from their clusters becoming field stars.

-Some star clusters may be interacting and eventually will merge.

We aim to study :

-Kinematic of the clusters, stars and the surrounding media: Chaotic? Small group interactions? How much the media affects to the clusters?

Is the velocity field of the gas coupled/de-coupled with the clusters ?

-Important information about the process of cluster disruptions

-Input for simulations.

ELT Justification: Only instrument available to reach objects of V=24 with s/n=30 using 3D spectroscopy. (Extrapolating VIMOS efficiency)

Legacy Value: Metallicity estimation of the clusters and the media. Ages and masses in combination with models can be also derived.

Data Reduction: 3D data skills.
