The authors found that the merger rate per unit redshift is nearly universal and independent of redshift, scaling simply with halo mass and mass ratio.

" The nearly universal merger rate of dark matter haloes in ΛCDM cosmology " Authors: Onsi Fakhouri and Chung-Pei Ma 13075x

The paper determines the merger rates of dark matter haloes as a function of halo mass, merger mass ratio, and redshift. The authors found that the merger rate per
