Abstract
We study the dynamical evolution of dense young star clusters formed within similar to 10 pc of the Galactic Center. Dynamical friction between the clusters and their surroundings causes them to sink toward the Galactic Center, ultimately leading to their disruption by tidal forces. During the inspiral, internal dynamical evolution drives the clusters toward core collapse; the most massive stars segregate to the cluster center while lower mass stars segregate to the cluster halo and are stripped by the Galactic field. If a cluster goes into deep core collapse before reaching the Galactic Center a collision runaway may occur, possibly resulting in the formation of an intermediate-mass black hole (IMBH) of several hundred solar masses.
