- Formation of globular clusters in galaxy mergers
- Bekki, Kenji; Couch, Warrick J.; Forbes, Duncan A.; Beasley, Michael A.
- Our numerical simulations first demonstrate that the pressure of ISM in a major merger becomes so high (> 10(5) k(B) K cm(-3)) that GMCs in the merger can collapse to form globular clusters (GCs) within a few Myr. The star formation efficiency within a GMC in galaxy mergers can rise up from a few percent to similar to 80 percent, depending on the shapes and the temperature of the GMC. This implosive GC formation due to external high pressure of warm/hot ISM can be more efficient in the tidal tails or the central regions of mergers. The developed clusters have King-like profiles with an effective radius of a few pc. The structural, kinematical, and chemical properties of these GC systems can depend on the orbital and chemical properties of major mergers.
