Universe, Large-Scale Structure

Scientific paper

These three lectures give an introduction to galaxy redshift surveys as probes of the large-scale structure in the Universe, and describe recent measurements of fundamental cosmological parameters from both the redshift surveys and observations of the cosmic microwave background. The first lecture deals with the large-scale structure (LSS) revealed by the galaxy distribution, and its interpretation in terms of cosmological parameters. The topics covered include: a descriptive review of large-scale structure; redshift surveys, cosmography and cosmology; the statistical characterization of LSS; an introduction to the theory of structure formation; the density and velocity fields; bias and the relation of light to mass; redshift-space distortions; the observed correlation function and power spectrum; and the Gaussianity and topology of the density field. The second lecture discusses the current state of the art in redshift surveys, describing the results on large-scale structure and cosmology emerging from the 2dF Galaxy Redshift Survey (2dFGRS). The third lecture discusses the important new results from observations of the cosmic microwave background (CMB) by the Wilkinson Microwave Anisotropy Probe (WMAP) satellite that were reported during the course of the Summer School.
