DEUS – Comoving Space Data

The datasets from the N-body simulations of different cosmological models, volumes and particle mass resolution can be accesses through the grid below. The simulated scenarios consist of a ΛCDM model, two quintessence dark energy models characterised by a Ratra-Peebles (RPCDM) and SUGRA (SUCDM) scalar potentials, and a wCDM model with a constant equation of state w = – 1.2. The cosmological parameters of these scenarios have been calibrated to the the WMAP-5yr and WMAP-7yr data respectively. The data files containing the cosmological parameter values and the cosmological functions characterising the expansion dynamics and the linear matter power spectrum are accessible through the corresponding links in the grid.
