Development of structure in a model universe containing unstable particles
Abstract
Computer analysis of a model universe containing unstable elementary particles discloses parameter domains for which the two-point galaxy autocorrelation function, the time scale for nonlinear evolution of structure, and the fractional mass in galaxy clusters and superclusters all are compatible with the observations. A low density for the cold missing-mass component can reconcile the low random velocities measured for galaxies in superclusters with inflationary-universe models having a critical mean density.
