Galactic Cannibalism: The link between dwarf galaxies and globular star clusters

银河系同类现象：矮小星系和球状星团之间的联系。在像我们银河系这样的巨大星系中，明亮的球状星团的形成仍然是天体物理学中一个悬而未决的问题。银河系自相残杀是一种理论，认为它们是由距离巨型星系引力场太近的矮小星系分裂而形成的。我们将使用新的双子座望远镜对球状星团、矮星系和我们新发现的超致密矮星系的性质进行敏感的比较，以检验这一理论，而超致密矮星系可能是这个过程中缺失的一环。

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.
