Gas density evolution (co-moving frame) part 2

We repeat this evolution. Note that the process of structure formation is ongoing right up to the present day.

The intersection of filaments produces regions of very high gas density, seen here in red, which are the sites for galaxy formation. Although galaxy formation is not included in this simulation, the spatial distribution of these high density peaks matches the observed galaxy cluster distribution quite well.
