Understanding the shape of the halo-mass and galaxy-mass cross-correlation functions

Hayashi, E., White, S. D. M.

Understand

We use the Millennium Simulation to measure the cross-correlation between halo centres and mass (or equivalently the average density profiles of dark haloes) in a LCDM cosmology.

  • We present results for radii in the range 10 kpc/h < r < 30 Mpc/h for halo masses in the range 4e10 Msol/h < M200 < 4e14 Msol/h.
  • Both at z=0 and at z=0.76 these cross-correlations are surprisingly well fit by approximating the inner region by a density profile of NFW or Einasto form, the outer region by a biased version of the linear mass autocorrelation function, and by adopting the maximum of the two where they are comparable.
  • We use a simulation of the formation of galaxies within the Millennium Simulation to explore how these results are reflected in cross-correlations between galaxies and mass.
