A study of dwarf galaxies in the core of a rich nearby cluster of galaxies shows that several of them require dark matter to remain stable
within the cluster's gravitational potential

Data from Hubble and the groundbased Gemini observatory provide evidence for the existence of an intermediate-mass black hole
in the globular cluster omega Centauri supporting a possible reclassification of the cluster as a dwarf galaxy
