omega-Cen - an Ultra Compact Dwarf Galaxy ?
  We study the merging of star clusters out of cluster aggregates similar to Knot S in the Antennae on orbits close to the one of omega-Cen by carrying out high resolution numerical N-body simulations. We want to constrain the parameter space which is able to produce merger objects with similar properties as omega-Cen.
