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.

Overconstrained dynamics in galaxy redshift surveys [PDF]
The Astrophysical Journal, 2001 The least-action principle (LAP) method is used on four galaxy redshift surveys to measure the density parameter Omega_m and the matter and galaxy-galaxy power spectra. The datasets are PSCz, ORS, Mark III and SFI.

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.

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.

Redshift Surveys With 2DF [PDF]
Highlights of Astronomy, 1998 This IAU Joint Discussion proposes to address the subject of redshift surveys in the 21st century. This paper, however, deals with two major new redshift surveys that those involved sincerely hope will be completed in the 20th century. Nonetheless, these surveys are relevant to the topic of the meeting, as they clearly foreshadow the scope and style of

Target Selection and Validation of DESI Luminous Red Galaxies
The Astronomical Journal, 2023 The Dark Energy Spectroscopic Instrument (DESI) is carrying out a five-year survey that aims to measure the redshifts of tens of millions of galaxies and quasars, including 8 million luminous red galaxies (LRGs) in the redshift range 0.4 < z ≲ 1.0.
