Constraining accuracy of the pairwise velocities in N -body simulations using scale-free models

ABSTRACT We present a continuation of an analysis that aims to quantify resolution of N-body simulations by exploiting large (up to N = 40963) simulations of scale-free cosmologies run using abacus. Here, we focus on radial pairwise velocities of the matter field, both by direct estimation and throu...
