Self-similar gravitational collapse in an expanding universe
Similarity solutions are derived which describe the collapse of cold, collisionless matter in a perturbed Einstein-de Sitter universe. Three classes of solutions are obtained, one each with planar, cylindrical, and spherical symmetry. These solutions can be computed to arbitrary accuracy, and they f...

Summary: | Similarity solutions are derived which describe the collapse of cold, collisionless matter in a perturbed Einstein-de Sitter universe. Three classes of solutions are obtained, one each with planar, cylindrical, and spherical symmetry. These solutions can be computed to arbitrary accuracy, and they follow the development of structure in both the linear and nonlinear regimes. |
