Abstract
We present the Millennium-II Simulation (MS-II), a very large N-body simulation of dark matter evolution in the concordance cold dark matter ( CDM) cosmology. The MS-II assumes the same cosmological parameters and uses the same particle number and output data structure as the original Millennium Simulation (MS), but was carried out in a periodic cube one-fifth the size (100 h -1 Mpc) with five times better spatial resolution (a Plummer equivalent softening of 1.0 h -1 kpc) and with 125 times better mass resolution (a particle mass of 6.9 10 6 h -1 M ). By comparing results at MS and MS-II resolution, we demonstrate excellent convergence in dark matter statistics such as the halo mass function, the subhalo…
