We measure the power spectrum of galaxy clustering in real space from the APM Galaxy Survey. We present an improved technique for the numerical inversion of Limber’s equation that relates the angular clustering of galaxies to an integral over the power spectrum in three dimensions. Our approach is underpinned by a large ensemble of mock galaxy catalogues constructed from the Hubble Volume N-body simulations. The mock catalogues are used to test for systematic effects in the inversion algorithm… 
The 2dF Galaxy Redshift Survey: power-spectrum analysis of the final data set and cosmological implications
We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS), employing a direct Fourier method. The sample used comprises 221 414 galaxies with measured redshifts. We
On Departures from a Power Law in the Galaxy Correlation Function
We measure the projected correlation function wp from the Sloan Digital Sky Survey for a flux-limited sample of 118,000 galaxies and a volume-limited subset of 22,000 galaxies with absolute magnitude
The Galaxy Angular Correlation Functions and Power Spectrum from the Two Micron All Sky Survey
We calculate the angular correlation function of galaxies in the Two Micron All Sky Survey. We minimize the possible contamination by stars, dust, seeing, and sky brightness by studying their cross
The shape of the sloan digital sky survey data release 5 galaxy power spectrum
We present a Fourier analysis of the clustering of galaxies in the combined main galaxy and LRG SDSS DR5 sample. The aim of our analysis is to consider how well we can measure the cosmological matter
The 2dF Galaxy Redshift Survey : higher-order galaxy correlation functions
We measure moments of the galaxy count probability distribution function in the Two-degree Field Galaxy Redshift Survey (2dFGRS). The survey is divided into volume-limited subsamples in order to
The 2dF Galaxy Redshift Survey: correlation functions, peculiar velocities and the matter density of the Universe
We present a detailed analysis of the two-point correlation function, xi(sigma, pi), from the 2dF Galaxy Redshift Survey (2dFGRS). The large size of the catalogue, which contains similar to220 000
Simulations of the formation, evolution and clustering of galaxies and quasars
It is shown that baryon-induced features in the initial conditions of the Universe are reflected in distorted form in the low-redshift galaxy distribution, an effect that can be used to constrain the nature of dark energy with future generations of observational surveys of galaxies.
Evidence of turbulence-like universality in the formation of galaxy-sized dark matter haloes
Context. Although the theoretical understanding of the nonlinear gravitational clustering has greatly advanced in the last dec ades, in particular by the outstanding improvement on numerical N-body
On measuring the covariance matrix of the non-linear power spectrum from simulations
We show how to estimate the covariance of the power spectrum of a statistically homogeneous and isotropic density field from a single periodic simulation, by applying a set of weightings to the
Interpreting the Observed Clustering of Red Galaxies at z ~ 3
Daddi et al. have recently reported strong clustering of a population of red galaxies at z � 3 in the Hubble Deep Field-South. Fitting the observed angular clustering with a power law of index � 0.8,


Power spectrum analysis of the Stromlo—APM redshift survey
We test estimators of the galaxy power spectrum P(k) against simulated galaxy catalogues constructed from N-body simulations, and we derive formulae to correct for biases. These estimators are then
The three-dimensional power spectrum measured from the APM Galaxy Survey – I. Use of the angular correlation function
We describe a method of recovering the three-dimensional power spectrum of galaxy clustering from measurements of the angular correlation function w(θ). We apply the technique to w(θ) measured from

Cluster correlations in redshift space
We test an analytic model for the two-point correlations of galaxy clusters in redshift space using the Hubble volume N-body simulations. The correlation function of clusters shows no enhancement

The three-dimensional power spectrum measured from the APM Galaxy Survey – II. Use of the two-dimensional power spectrum
We present the results of a Fourier transform analysis of galaxies from the APM Survey in the magnitude range 17≤b J ≤20. The two-dimensional power spectrum of galaxy clustering is found to obey a
