Measuring our Universe from Galaxy Redshift Surveys [PDF]

open access: yesLiving 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.

Cosmology with Redshift Surveys of Radio Sources [PDF]

open access: yes, 1998
We use the K-z relation for radio galaxies to illustrate why it has proved difficult to obtain definitive cosmological results from studies based entirely on catalogues of the brightest radio sources, e.g. 3C. To improve on this situation we have been undertaking redshift surveys of complete samples drawn from the fainter 6C and 7C radio catalogues. We

The miniJPAS survey: Photometric redshift catalogue [PDF]

open access: yesAstronomy & 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 ...

Redshift Surveys With 2DF [PDF]

open access: yesHighlights 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

First results from high redshift quasar searches in VIKING [PDF]

open access: yes, 2012
This thesis presents the discovery of the first luminous z & 6.5 quasars in the VISTA kilo-degree Infrared Galaxy Survey (VIKING). After some basic quality control, quasar selection is investigated via use of initial data supplementedwith ...

Target Selection and Validation of DESI Quasars

open access: yesThe 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.

The 2dF Galaxy Redshift Survey: spectra and redshifts [PDF]

open access: yesMonthly 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 ...

Target Selection and Validation of DESI Luminous Red Galaxies

open access: yesThe 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.

Hydra — Centaurus: A Redshift Survey [PDF]

open access: yesSymposium - International Astronomical Union, 1988
The survey consists of 2 samples : SAMPLE A, 85% complete to B(T) = 14.0 in the region between 10 and 14 Hours in R.A. and between −20 and −50 degrees in DEC., SAMPLE B, complete to B(0) = 14.5 in two regions one between R.A. 13 and 14 hours, DEC between −25 and −33, the other between 11 and 12 hours, DEC from −33 to −27.
