Galaxy Mergers with Adaptive Mesh Refinement: Star Formation and Hot Gas Outflow

  Ji-hoon Kim [Home], John H. Wise, and Tom Abel  (arXiv:0902.3001)

1. Parameters and Documentations

  - Two 1.8e10 Ms galaxy progenitors with 10% in gas set on a coplanar hyperbolic collision orbit, Evolved for 6.0 Gyrs
  - Radiative cooling, Star formation and feedback, Resolved by ~2e7 computational elements with finest resolution of 3.8 pc
  - For details, see the abstract or my ApJ Letter (high-resolution). Also, my 1-hour talk given in JILA Lunch@CU Boulder can be of your interest.
