Early Growth in a Perturbed Universe: Exploring Dark Matter Halo Populations in 2LPT and ZA Simulations
We study the structure and evolution of dark matter halos from z = 300 to z = 6 for two cosmological N-body simulation initialization techniques. While the second-order Lagrangian perturbation theory (2LPT) and the Zel'dovich approximation (ZA) both produce accurate present day halo mass functi...
