The Two - Point Correlation Function at Redshift
We present the results of a study of the two-point correlation function for a sample of field galaxies taken from the CNOC cluster survey. The sample consists of 144 galaxies within a contiguous region of space subtending 225 square arcminutes. The objects have r-band magnitudes 17.0 ≤ r ≤ 21.7 and redshifts 0.21 ≤ z ≤ 0.53. The median redshift of the sample is z̄ = 0.36. The real space correlat...

متن کاملNonlinear 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-linear effects which arise as a consequence of the map from real to redshift space. Our result is non-perturbative and it includes the effects of possible multi-streaming in redshift space. We find that the de...
متن کاملRedshift Evolution of the Nonlinear Two-Point Correlation Function
This paper presents a detailed theoretical study of the two-point correlation function ξ for both dark matter halos and the matter density field in five cosmological models with varying matter density Ωm and neutrino fraction Ων . The objectives of this systematic study are to evaluate the nonlinear gravitational effects on ξ, to contrast the behavior of ξ for halos vs. matter, and to quantify ...
متن کاملThe Durham / UKST Galaxy Redshift Survey - IV . Redshift Space Distortions in the 2 - Point Correlation Function
We have investigated the redshift space distortions in the optically selected Durham/UKST Galaxy Redshift Survey using the 2-point galaxy correlation function perpendicular and parallel to the observer's line of sight, ξ(σ, π). We present results for the real space 2-point correlation function, ξ(r), by inverting the optimally estimated projected correlation function, which is obtained by integ...
