Structure formation in the quasi-spherical Szekeres model |
Abstract _ |
Structure formation in the quasi-spherical Szekeres model is investigated. It is an exact solution of the Einstein field equations, which represents a time-dependent mass dipole superposed on a monopole. Therefore it is suitable for modeling double structures such as a void and an adjourning galaxy supercluster. The Szekeres model makes it possible to examine interactions between the considered structures. This paper presents evolutionary models of voids and adjourning galaxy superclusters. It has been found that voids play significant role in the process of cluster formation. The mass flow from voids to clusters enhances the growth of the density contrast. |
