How Did Globular Clusters Form
@article{Bergh2001HowDG, title={How Did Globular Clusters Form}, author={Sidney van den Bergh}, journal={The Astrophysical Journal}, year={2001}, volume={559} }
It is suggested that there have been at least two physically distinct epochs of massive cluster formation. The first generation of globular clusters may have formed as halo gas was compressed by shocks driven inward by ionization fronts generated during cosmic reionization at z ~ 6. On the other hand, a second generation of massive clusters might have been formed at later times by compression, and subsequent collapse, of giant molecular clouds. In some cases this compression may have been…

The evolution of star clusters is largely affected by the tidal field generated by the host galaxy. It is thus in principle expected that under the assumption of an "universal" initial cluster mass…
