Galactic Cannibalism: The link between dwarf galaxies and globular star clusters. The formation of bright globular star clusters in giant galaxies like our own Milky Way remains an unsolved problem in astrophysics. Galactic cannibalism is the theory that they formed by the disruption of dwarf galaxies that came too close to the gravitational field of giant galaxies. We will use the new Gemini Telescopes to test this theory with sensitive comparisons of the properties of globular clusters, dwarf galaxies and our newly-discovered ultra-compact dwarf galaxies which may be the missing link in this process.

银河同类相食：矮星系和球状星团之间的联系。像我们银河系这样的巨型星系中明亮的球状星团的形成仍然是天体物理学中尚未解决的问题。银河同类相食理论认为，矮星系因过于接近巨星系的引力场而破裂而形成。我们将使用新的双子座望远镜来测试这一理论，对球状星团、矮星系和我们新发现的超紧凑矮星系的特性进行敏感的比较，这可能是这个过程中缺失的一环。
