Constraints on Ω from the IRAS redshift surveys [PDF]
, 1995 We measure the anisotropy of the redshift-space power spectrum in the 1.2-Jy and QDOT redshift surveys of IRAS-selected galaxies. On large scales, this anisotropy is caused by coherent peculiar motions, and gravitational instability theory predicts a ...

The Anglo-Australian Redshift Survey [PDF]
Symposium - International Astronomical Union, 1983 The aim of the survey is to sample a relatively large, randomly chosen volume of the Universe in order to study the large-scale distribution of galaxies using the two-point correlation function, the peculiar velocities between galaxy pairs and to provide an estimate of the galaxian luminosity function that is unaffected by density inhomogeneities and ...

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.

Simulations of deep redshift surveys
, 1990 Magnitude-limited redshift samples drawn from numerical simulations of the biased cold dark matter model are presented, with geometry matched to the recent survey by Geller and Huchra.

Cosmological inference from Bayesian forward modelling of deep galaxy redshift surveys [PDF]
Astronomy & Astrophysics, 2018 We present a large-scale Bayesian inference framework to constrain cosmological parameters using galaxy redshift surveys, via an application of the Alcock-Paczyński (AP) test.

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.

The 2dF Galaxy Redshift Survey: spectra and redshifts [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 The 2dF Galaxy Redshift Survey (2dFGRS) is designed to measure redshifts for approximately 250 000 galaxies. This paper describes the survey design, the spectroscopic observations, the redshift measurements and the survey data base. The 2dFGRS uses the 2dF multifibre spectrograph on the Anglo-Australian Telescope, which is capable of observing 400 ...
