Globular clusters are some of the most massive and densest star clusters observed. What are the progenitors of old globular clusters that we see orbiting the Milky Way and other galaxies? What evolutionary and dynamical effects have these clusters experienced? What determines the physical properties of old globular clusters? Why are there two “distinct” classes of globular clusters and what properties determine these physical states? These are the questions the authors aim to answer.
