  • Conference proceeding on how the MW is special in the sense that it forms little stars and therefore cannot have undergone a merger for a long time.

  • The GCs around Andromeda rotate.
  • GCs can be “friendless”, meaning they have no neighbors with similar kinematics. In addition they look at various subsamples depending e.g. on metallicity and brightness.

  • Combining gravitational lensing and galaxy dynamics (velocity dispersion as a funciton of radius in ellipticals) as a new and independant (!) method of measuring the geometry of the universe.
  • Way cool, if it ever gets on par in accuracy with the other methods.
