Peebles Isocurvature Baryon Cosmogony: Caption
Time Evolution
This landmark simulation was one of the first to model in all three spatial
dimenstions the behavior of "ordinary" baryonic matter at the supercluster
scale. However, dark matter particle-mesh technique was employed for this
purpose, as an approximation for modelling gas dynamics. The resolution is
fairly low, permitting modelling only of large-scale structures beyond
even the size of galaxy clusters. Two movies are shown: the first depicts the time evolution
of the volume modelled; the second, a slice through the simulated volume
corresponding to a redshift of zero, i.e. the appearance of the universe today, as predicted by the model. The results
are directly comparable to
observations of large-scale structures via red-shift surveys of the
cosmos.
