Abstract

In the past, the standard method of analysing temperature and polarization anisotropies imprinted into the Cosmic Microwave Background by large-scale structure was to use approximate perturbative techniques applied to a Friedmann-Robertson-Walker model. Instead, this thesis researches models based on exact inhomogeneous solutions of the Einstein field equations, such as the Lematre-Tolman (spherically symmetric with dust source) and Szekeres models (non-symmetric), to see whether there might be effects arising from large inhomogeneities that are missed in the standard approach. 1
