The 4D universe project




The aim of the following movies is to give an insight on the formation of  structures occuring in a LCDM universe, in particular the formation of large scale structures, galaxy clusters and disk galaxies. The simulations have been performed using a modified version of the Gadget-2 cosmological code (Springel 05) including basic baryon physics (cooling, heating, star formation and supernovae feedback). The simulated box represents a co-volume of 20 (Mpc/h)^3, containing 33'554'432 particles (half being gas), reaching a resolution of about 2 kpc/h. The universe model corresponds to the concordance univers model, using the parameters mesured by WMAP III. The movies have been realized using the Python Parallelized N-body Toolbox (pNbody-4.0). Only the gaseous particles are represented in the movies. Except for the last movie, each movie can be display in stereo, using red-cyan glasses. Stereo movies designed for geowall systems may be optained on demand.
