In this paper, the authors investigate how the halo mass function evolves with redshift, based on a suite of very large cosmological N-body simulations, using both the Friends-of-Friends (FOF) and Spherical Overdensity (SO) halofinding methods to compare the mass function derived using these commonly used halo definitions.Abstract:
In this paper we investigate how the halo mass function evolves with redshift, based on a suite of very large (with N_p = 3072^3 - 6000^3 particles) cosmological N-body simulations Our halo catalogue data spans a redshift range of z = 0-30, allowing us to probe the mass function from the dark ages to the present We utilise both the Friends-of-Friends (FOF) and Spherical Overdensity (SO) halofinding methods to directly compare the mass function derived using these commonly used halo definitions The mass function from SO haloes exhibits a clear evolution with redshift, especially during the recent era of dark energy dominance (z 20, the SO algorithm finds a ~50-80% lower collapsed fraction in high mass haloes than does the FOF algorithm, due in part to the significant over-linking effects known to affect the FOF methodread more

A Universal Density Profile from Hierarchical Clustering
TL;DR: In this article, the authors used high-resolution N-body simulations to study the equilibrium density profiles of dark matter halos in hierarchically clustering universes, and they found that all such profiles have the same shape, independent of the halo mass, the initial density fluctuation spectrum, and the values of the cosmological parameters.
