Clustering in real space and in redshift space

TL;DR: In this paper, a principal component analysis is performed to assess the ability of future observations to measure departures from General Relativity in predictions of the Poisson and anisotropy equations on linear scales.

TL;DR: In this paper, the transverse power spectrum and the corresponding correlation function can be measured from observations alone and that these contain the full three dimensional information, and the two point galaxy correlation function at linear order in perturbation theory.

TL;DR: In this article, a double power-law ξ(r) oc r -γ model was proposed for clustering in the 2dF Galaxy Redshift Survey (2dFGRS).

TL;DR: In this article, a caustic technique was used to identify 275 cluster members within 7 h 1/Mpc of the hierarchical cluster center. But the caustics were not applied to the Brightest Cluster Galaxy (BCG).
