Zel'dovich approximation

(model of the formation of cosmological structure)

The Zel'dovich approximation is a model of the formation of the grand structure of the universe applying Lagrangian perturbation theory. It was published in 1970 by Soviet physicist Yakov Zel'dovich (also known for the Sunyaev-Zel'dovich effect). Zel'dovich pancakes are an ellipsoid/pancake-shaped high-density volumes which his model produces and he suggested were seeds of large scale structures such as superclusters.
