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.

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.

Forecasting Cosmological Constraints from Redshift Surveys [PDF]
Monthly Notices of the Royal Astronomical Society, 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.

On estimating redshift and luminosity distributions in photometric redshift surveys [PDF]
, 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

Topological Approach to Void Finding Applied to the SDSS Galaxy Map [PDF]
The Astrophysical JournalThe structure of the low redshift Universe is dominated by a multiscale void distribution delineated by filaments and walls of galaxies. The characteristics of voids, such as morphology, average density profile, and correlation function, can be used as ...

The miniJPAS survey: Photometric redshift catalogue [PDF]
Astronomy & Astrophysics, 2021 MiniJPAS is a ∼1 deg2 imaging survey of the AEGIS field in 60 bands, performed to demonstrate the scientific potential of the upcoming Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS). Full coverage of the 3800–9100 Å range with 54 narrow-band filters, in combination with 6 optical broad-band filters, allows for extremely ...

Target Selection and Validation of DESI Quasars
The Astrophysical Journal, 2023 The Dark Energy Spectroscopic Instrument (DESI) survey will measure large-scale structures using quasars as direct tracers of dark matter in the redshift range 0.9 < z < 2.1 and using Ly α forests in quasar spectra at z > 2.1.
