1. Parameters and Documentations

  - A 9.2e11 Ms galactc halo identified at z=3 in a cosmological LCDM simulation, Evolved for 350 Myrs
  - Radiative cooling, 6-species chemistry, molecular cloud (MC) formation and feedback at the finest resolution of 15.2 pc
  - Massive black hole (MBH) accretion and feedback: radiative (3D ray tracing coupled with hydro) and mechanical (bipolar jets resolved in AMR)
  - For details, see the abstract or my ApJ Paper (high-resolution).
