FoF Halo Catalog: Horizon Run 4 Simulation


This is the FoF halo catalogs in Horizon Run 4 simulation (Kim, Park, L'Huillier & Hong 2015).

Horizon Run 4 simulation is a cosmological N-body simulation with the following properties:

  • Box size: (3,150 cMpc/h)3
  • Number of matter particles: 6,3003
  • Cosmology: WMAP 5-year ΛCDM cosmology; (Ωm, ΩΛ, h, σ8, ns) = (0.26, 0.74, 0.72, 0.79, 0.96)

FoF halos have the following properties:

  • Linking length: 0.1 cMpc/h
  • Minimum number of member particles: 30
  • Minimum FoF halo mass: 2.7×1011 Msun/h


Each data file has a name as halo.z[redshift]_[lowest Log(M)]_[highest Log(M)].hdf5. Note that the halos in each file are not sorted by their mass. Each data file is written as HDF5 file format containing the following properties:

  • ID: Halo index
  • x, y, z: Position in comoving coordinate (cMpc/h)
  • vx, vy, vz: Peculiar velocity (km/s)
  • mass: Halo mass (Msun/h)
