Abstract

The model of the Big Bang is the fundamental theoretical scenario for the understanding of how the universe envolved from a n extreme uniformity to a great richness of structures cotaining galaxies, clusters of galaxies, super clusters of galaxies, voids and walls of galaxies, creating also as a by product of its evolution, the cosmic microwave background radiation (CMBR). This project has as its objective theoretical/observational studies in the universe in order to understand better and more precise the physical phenomena responsible for the formation of the structures that we observe today in the universe. These studies will be made by means of theoretical analysis, numerical simulations, observations of the angular distribution of the CMBR and the large scale structure of the universe. AU) (AU)
