The 2MASS Redshift Survey in the Zone of Avoidance [PDF]

open access: yesAstrophysical Journal Supplement Series, 2019
The Two Micron All-Sky Survey (2MASS) Redshift Survey was started two decades ago with the goal of mapping the three-dimensional distribution of an all-sky flux-limited (Ks < 11.75 mag) sample of ∼45,000 galaxies.

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

open access: yes, 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.

HectoMAP: The Complete Redshift Survey (Data Release 2)

open access: yesThe Astrophysical Journal, 2023
HectoMAP is a dense redshift survey of 95,403 galaxies based primarily on MMT spectroscopy with a median redshift z = 0.345. The survey covers 54.64 deg ^2 in a 1.°5 wide strip across the northern sky centered at a decl. of 43.°25. We report the redshift,

The 2dF Galaxy Redshift Survey: power-spectrum analysis of the final data set and cosmological implications [PDF]

open access: yes, 2005
We present a power-spectrum analysis of the final 2dF Galaxy Redshift Survey (2dFGRS), employing a direct Fourier method. The sample used comprises 221 414 galaxies with measured redshifts.

Target Selection and Sample Characterization for the DESI LOW-Z Secondary Target Program

open access: yesThe Astrophysical Journal, 2023
We introduce the DESI LOW- Z Secondary Target Survey, which combines the wide-area capabilities of the Dark Energy Spectroscopic Instrument (DESI) with an efficient, low-redshift target selection method.

The VIMOS Public Extragalactic Redshift Survey (VIPERS). Full spectroscopic data and auxiliary information release (PDR-2) [PDF]

open access: yes, 2016
We present the full public data release (PDR-2) of the VIMOS Public Extragalactic Redshift Survey (VIPERS), performed at the ESO VLT. We release redshifts, spectra, CFHTLS magnitudes and ancillary information (as masks and weights) for a complete sample ...

The SAMI Galaxy Survey: the cluster redshift survey, target selection and cluster properties [PDF]

open access: yes, 2017
We describe the selection of galaxies targeted in eight low-redshift clusters (APMCC0917, A168, A4038, EDCC442, A3880, A2399, A119 and A85; 0.029 < z < 0.058) as part of the Sydney-AAO Multi-Object Integral field spectrograph Galaxy Survey (SAMI-GS).

The VIMOS Public Extragalactic Redshift Survey (VIPERS): galaxy segregation inside filaments at z ≃ 0.7 [PDF]

open access: yes, 2016
We present the first quantitative detection of large-scale filamentary structure at z ≃ 0.7 in the large cosmological volume probed by the VIMOS Public Extragalactic Redshift Survey (VIPERS). We use simulations to show the capability of VIPERS to recover
