Large-scale structure from galaxy and cluster surveys

I review the status of large-scale structure studies based on large redshift surveys of galaxies and clusters of galaxies. In particular, I compare results on the power spectrum and two-point correlation correlation function from the 2dF and REFLEX surveys, highlighting the advantage of X-ray clusters in the comparison to cosmological models, given their easy-to-understand mass selection function. I also mention recent measurements of the matter density parameter from redshift space distortions in galaxy surveys, and show evidence for similar streaming motions of clusters in the REFLEX redshift-space correlation function xi(r(p), pi). The overall picture shows a remaxkable consistency of independent clustering data and measurements towards the same low-density CDM model with Omega(M) similar or equal to 0.3.
