Abstract

We construct merger trees of dark matter haloes and quantify their merger rates and mass growth rates using the joint data set from the Millennium and Millennium-II simulations. The finer resolution of the Millennium-II simulation has allowed us to extend our earlier analysis of halo merger statistics to an unprecedentedly wide range of descendant halo mass (1010≲M0≲ 1015 M⊙), progenitor mass ratio (10−5≲ξ≤ 1) and redshift (0 ≤z≲ 15). We update our earlier fitting form for the mean merger rate per halo as a function of M0, ξ and z. The overall behaviour of this quantity is unchanged: the rate per unit redshift is nearly independent of z out to z∼ 15; the dependence on halo mass is weak (∝M0.130); and it is nearly a power law in the progenitor mass ratio (∝ξ−2). We also present a simple and accurate fitting formula for the mean mass growth rate of haloes as a function of mass and redshift. This mean rate is 46 M⊙ yr−1 for 1012 M⊙ haloes at z= 0, and it increases with mass as ∝M1.1 and with redshift as (1 +z)2.5 (for z≳ 1). When the fit for the mean mass growth rate is integrated over a halo's history, we find excellent match to the mean mass assembly histories of the simulated haloes. By combining merger rates and mass assembly histories, we present results for the number of mergers over a halo's history and the statistics of the redshift of the last major merger.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
