Clustering studies with the 2dF galaxy redshift survey

Abstract

The 2dF Galaxy Redshift Survey has now been completed and has mapped the three-dimensional distribution, and hence clustering, of galaxies in exquisite detail over an unprecedentedly large ($\sim 10^{8} h^{-3}$ Mpc$^{3}$) volume of the local Universe. Here we highlight some of the major results to come from studies of clustering within the survey: galaxy correlation function and power spectrum analyses and the constraints they have placed on cosmological parameters; the luminosity functions of rich galaxy clusters, their dependence on global cluster properties and galaxy type, and how they compare with the field; and the variation of galactic star formation activity with environment, both within clusters and in galaxy groups.
