Kinematics of Globular Clusters in the Fornax Cluster

The Fornax cluster provides an unparalleled opportunity to investigate the formation and evolution of galaxies in a dense environment in great detail. Using the VLT/VIMOS spectroscopic survey of the Fornax cluster, we confirm the detection of 777 globular clusters (GCs). Combined with previous measurements, this leads to the most extensive catalog of radial velocity measurements of a total of 2341 GCs in Fornax. This VIMOS spectroscopic survey allowed the kinematical characterization of photometrically discovered substructures in the GC distribution. We found that metal-rich (red) GCs are concentrated around the major galaxies, while metal-poor (blue) GCs are kinematically irregular and widely spread throughout the core region of the cluster
