Measuring our Universe from Galaxy Redshift Surveys [PDF]
Living Reviews in Relativity, 2004 Galaxy redshift surveys have achieved significant progress over the last couple of decades. Those surveys tell us in the most straightforward way what our local Universe looks like.

On estimating redshift and luminosity distributions in photometric redshift surveys [PDF]
Monthly Notices of the Royal Astronomical Society, 2007 The luminosity functions of galaxies and quasars provide invaluable information about galaxy and quasar formation. Estimating the luminosity function from magnitude limited samples is relatively straightforward, provided that the distances to the objects

The Nonlinear Redshift Space Power Spectrum: Omega from Redshift Surveys [PDF]
Monthly Notices of the Royal Astronomical Society, 1995 We examine the anisotropies in the power spectrum by the mapping of real to redshift space. Using the Zel'dovich approximation, we obtain an analytic expression for the nonlinear redshift space power spectrum in the distant observer limit.

The Redshift Distribution of the TOUGH Survey [PDF]
EAS Publications Series, 2013 We present the redshift results from a Very Large Telescope (VLT) program aimed at optimizing the legacy value of the Swift mission: to characterize a homogeneous, X-ray selected, sample of 69 GRB host galaxies. Fifteen new redshifts have been secured, resulting in a 77% (53/69) redshift completion, making the survey the most comprehensive in terms of

Beyond the plane-parallel approximation for redshift surveys [PDF]
, 2018 Redshift space distortions privilege the location of the observer in cosmological redshift surveys, breaking the translational symmetry of the underlying theory.

Bayesian inference from photometric redshift surveys [PDF]
, 2011 We show how to enhance the redshift accuracy of surveys consisting of tracers with highly uncertain positions along the line of sight. Photometric surveys with redshift uncertainty delta_z ~ 0.03 can yield final redshift uncertainties of delta_z_f ~ 0 ...

Recovering the real-space correlation function from photometric redshift surveys [PDF]
, 2008 Measurements of clustering in large-scale imaging surveys that make use of photometric redshifts depend on the uncertainties in the redshift determination.

Measuring the Universe with Galaxy Redshift Surveys [PDF]
, 2018 Galaxy redshift surveys are one of the pillars of the current standard cosmological model and remain a key tool in the experimental effort to understand the origin of cosmic acceleration. To this end, the next generation of surveys aim at achieving sub-percent precision in the measurement of the equation of state of dark energy $w(z)$ and the growth ...

Power spectrum analysis of three-dimensional redshift surveys [PDF]
, 1993 We develop a general method for power spectrum analysis of three dimensional redshift surveys. We present rigorous analytical estimates for the statistical uncertainty in the power and we are able to derive a rigorous optimal weighting scheme under the ...

Forecasting Cosmological Constraints from Redshift Surveys [PDF]
, 2008 Observations of redshift-space distortions in spectroscopic galaxy surveys offer an attractive method for observing the build-up of cosmological structure, which depends both on the expansion rate of the Universe and our theory of gravity.
