We present the large-scale correlation function measured from a spectroscopic sample of 46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers 0.72 h-3 Gpc3 over 3816 deg2 and 0.16 < z < 0.47, making it the best sample yet for the study of large-scale structure. We find a well-detected peak in the correlation function at 100 h-1 Mpc separation that is an excellent match to the predicted shape and location of the imprint of the recombination-epoch acoustic… 


The correlation function of the distribution of matter in the universe shows, at large scales, baryon acoustic oscillations, which were imprinted prior to recombination. This feature was first

An improved measurement of baryon acoustic oscillations from the correlation function of galaxy clusters at z ∼ 0.3

We detect the peak of baryon acoustic oscillations (BAO) in the two-point correlation function of a spectroscopic sample of $25226$ clusters selected from the Sloan Digital Sky Survey. Galaxy

Clustering of luminous red galaxies – III. Baryon acoustic peak in the three-point correlation

We present the three-point function ξ 3 and Q 3 = ξ 3 /ξ 2 2 for a spectroscopic sample of luminous red galaxies from the Sloan Digital Sky Survey (SDSS) Data Release 6 and Data Release 7. We find a


We examine the correlation function ξ of the Sloan Digital Sky Survey Luminous Red Galaxy sample at large scales (60 h−1 Mpc < s < 400 h−1 Mpc) using the final data release (DR7). Focusing on a

We present the first scientific results from the luminous red galaxy (LRG) sample of the extended Baryon Oscillation Spectroscopic Survey (eBOSS) combined with the high-redshift galaxies of the

Absence of anti-correlations and of baryon acoustic oscillations in the galaxy correlation function from the Sloan Digital Sky Survey data release 7

Aims. One of the most striking features predicted by standard models of galaxy formation is the presence of anti-correlations in the matter distribution on large enough scales (r > rc). Simple

Clustering of photometric luminous red galaxies – II. Cosmological implications from the baryon acoustic scale

A new determination of the sound horizon scale is presented. It makes use of 1:5 10 6 luminous red galaxies, selected from the Sloan Digital Sky Survey imaging data, with photometric redshifts. The

The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger volume than the combined efforts of

The Anisotropic Redshift Space Galaxy Correlation Function: Detection on the BAO Ring

In a series of papers we have recently studied the clustering of Luminous Red Galaxies (LRG’s) in the latest spectroscopic Sloan Digital Sky Survey (SDSS) data release, which has 75,000 LRG’s



Possible Detection of Baryonic Fluctuations in the Large-Scale Structure Power Spectrum

We present a joint analysis of the power spectra of density fluctuations from three independent cosmological redshift surveys: the IRAS Point Source redshift catalog (PSCz) galaxy survey, the

Large-Scale Clustering of Sloan Digital Sky Survey Quasars: Impact of the Baryon Density and the Cosmological Constant

We report on the first result from the clustering analysisof SDSS quasars. We computed the two-point correlation function (2PCF) of SDSS quasars in redshift space at 8 h −1 Mpc <s <500 h −1 Mpc, with

We show that the measurement of the baryonic acoustic oscillations in large high-redshift galaxy surveys offers a precision route to the measurement of dark energy. The cosmic microwave background

Determination of the Baryon Density from Large-Scale Galaxy Redshift Surveys

We estimate the degree to which the baryon density, Ωb, can be determined from the galaxy power spectrum measured from large-scale galaxy redshift surveys, and in particular, the Sloan Digital Sky

We compute the real-space power spectrum and the redshift-space distortions of galaxies in the 2dF 100k galaxy redshift survey using pseudo-Karhunen-Loeve eigenmodes and the stochastic bias

The Luminosity and Color Dependence of the Galaxy Correlation Function

The HOD model fits nicely explain the color dependence of wp(rp) and the cross correlation between red and blue galaxies, and a conditional luminosity function (at fixed halo mass) in which central galaxies lie far above a Schechter function extrapolation of the satellite population.
