Constraining the Cosmological Constant from Large-Scale Redshift-Space Clustering

Abstract: We show how the cosmological constant can be estimated from redshift surveys at different redshifts, using maximum-likelihood techniques. The apparent redshift-space clustering on large scales ( > ∼ 20 h −1 Mpc ) are affected in the radial direction by infall, and curvature influences the apparent correlations in the transverse direction. The relative strengths of the two effects will strongly vary with redshift. Using a simple idealized survey geometry, we compute the smoothed correlation matrix of the redshi… Show more

“…Alcock & Paczynski (1979;hereafter AP) proposed an idealized cosmological test using this idea, based on a hypothetical population of intrinsically spherical galaxy clusters. The AP test can be implemented in practice by using the amplitude of quasar or galaxy clustering to identify equivalent scales in the angular and redshift dimensions (Ballinger et al, 1996;Matsubara and Suto, 1996;Popowski et al, 1998;Matsubara and Szalay, 2001) or by using anisotropy of clustering in the Lyα forest McDonald and Miralda-Escudé, 1999). AP measurements provide a cosmological test in their own right, and they allow high-redshift distance measurements to be translated into constraints on H(z), which is a more direct measure of energy density.…”
