WebNov 1, 2012 · The shape of the CDM power spectrum results in a hierarchical, bottom-up process of structure formation, in which small and low mass objects collapse first and over time merge to form ever more massive structures, until the onset at z ≈ 1 of DE induced accelerated expansion begins to halt further collapse. In Fig. 1 we show a plot of the …
