The cosmic evolution of the clustering of galaxies

The clustering of faint galaxies is studied using two complementary approaches: the angular (2-D) correlation function and the spatial (3-D) correlation function. The two-point angular correlation function, ;An analogous 3-D approach is used to study the evolution of the correlation length with epoch for the 591 objects in the CFRS that have secure redshifts. The projected correlation function, ;Clustering as a function of colour is studied by dividing the CFRS into blue and red sub-samples. The blue and red sub-samples are found to cluster similarly at high redshifts while the blue galaxies cluster more weakly at low redshift.;The implications of these new results are discussed in the context of our understanding of the nature of the faint galaxy population.
