We study the distortions induced by peculiar velocities on the redshift-space correlation function of galaxies of different morphological types in the Pisces-Perseus redshift survey. Redshift-space distortions affect early- and late-type galaxies in different ways. In particular, at small separations the dominant effect comes from virialized cluster cores, where ellipticals are the dominant population. The net result is that a meaningful comparison of the clustering strength of different… Expand

The Redshift-Space Two-Point Correlation Functions of Galaxies and Groups in the Nearby Optical Galaxy Sample
We use the two-point correlation function in redshift space, ξ(s), to study the clustering of the galaxies and groups of the Nearby Optical Galaxy (NOG) sample, which is a nearly all-sky (|b| > 20°),Expand

Linear redshift distortions: A Review
Redshift maps of galaxies in the Universe are distorted by the peculiar velocities of galaxies along the line of sight. The amplitude of the distortions on large, linear scales yields a measurementExpand
Non‐linear redshift distortions: the two‐point correlation function
We consider a situation where the density and peculiar velocities in real space are linear, and we calculate ξs, the two-point correlation function in redshift space, incorporating all non-linearExpand
