Overview

This page provides details about the data release in conjunction with Diemer 2022. This paper presents simulated halo density profiles split into an orbiting and an infalling component based on the orbit of each particle. The data is computed using the SPARTA code.

The full data will be made available here as soon as the paper is accepted for publication. If you would like to use them in the meantime, please contact me.

Additional figures

In the journal paper, I could show only a tiny subset of the rich set of density profiles for halos with different mass (peak height), mass accretion rate, redshift, and in different LCDM and self-similar cosmologies. The following figures show a more complete picture. For simplicity, the figures are grouped into a few .zip files:

  • data_profiles_lcdm_nu.zip: mean and median profiles binned by peak height, for each cosmology and redshift. There are two sets of figures, where the profiles are separated into columns of redshift or peak height (nu). The former is designed for comparisons across peak heights and the latter for comparisons across redshift. The filenames are
    profiles_<cosmo>_col<z,nu>_<md,mn>.pdf
    where “md” and “mn” indicate median and mean profiles, and possible cosmologies are “wmap7” or “planck” (see paper for the cosmological parameters).
  • data_profiles_lcdm_nu_gamma.zip: mean and median profiles binned by both peak height and accretion rate. Each figure shows one redshift (z = 0, 1, 2, 4). The filenames are
    profiles_<cosmo>_colGamma_z<z>.pdf
  • data_profiles_selfsim.zip: the “selfsim” case refers to self-similar Einstein-de Sitter universes that are distinguished only by their power spectrum slope, n. Due to the self-similarity over cosmic time, all redshifts are combined for those simulations. The filenames are
    profiles_selfsim_col<n,nu>_<md,mn>.pdf (all n, binned by peak height only, columns of nu or n)
    profiles_selfsim_colGamma_nu_<from>_<to>_<md,mn>.pdf (all n, binned by peak height and acc. rate)
    profiles_<cosmo>_colGamma_<md,mn>.pdf (one file per n)
    In the last set of files, the cosmology can be “ss10”, “ss15”, “ss20”, and “ss25”, which stand for the self-similar cosmologies with n = -1 / -1.5 / -2 / -2.5.
  • data_profiles_cosmo.zip: direct comparison of profiles for the WMAP7 cosmology at z = 0 and z = 4 and the self-similar cosmologies with n = -1.5 and n = -2.5. The filenames are
    profiles_cosmocomp_col<nu,Gamma>_nu_<from>_<to>_<md,mn>.pdf
  • data_profile_scatter.zip: 1-sigma scatter around the median profiles. The filenames are
    scatter_<cosmo>_col<z,Gamma,n>_z<z>.pdf
