These lectures deal with our current knowledge of the matter distribution in the universe, focusing on how this is studied via the large-scale structure seen in galaxy surveys. We first assemble the necessary basics needed to understand the development of density fluctuations in an expanding universe, and discuss how galaxies are located within the dark-matter density field. Results from the 2dF Galaxy Redshift Survey are presented and contrasted with theoretical models. We show that the… 
Cosmological Features of Primordial Magnetic Fields
Recently, it has been found that our Universe holds magnetic fields in almost all scales probed so far. The fields in galaxies and galaxy clusters have strength of a few μGauss and they are

CONFORMAL SCALING GAUGE SYMMETRY AND INFLATIONARY UNIVERSE
Considering the conformal scaling gauge symmetry as a fundamental symmetry of nature in the presence of gravity, a scalar field is required and used to describe the scale behavior of the universe. In
