Large-scale structure of the Universe: three-dimensional numerical models

As follows from observations, galaxies and their cluster are grouped into large flattened or filamentary systems, known as superclusters. Development of a large-scale structure of the Universe, comprising superclusters is studied by three-dimensional numerical simulation method. The program allows one to simulate the movement of collisionless matter under the gravitational force effect in the extending Universe. Optimization intended for applying vector operations in the Cray-1 supercomputer, using which the present work is performed, is used in the program. The resulting models clearly demonstrate the formation of clusters and superclusters as the Universe develops. 54 refs.; 12 figs
