The DEEP2 Galaxy Redshift Survey: Redshift Identification of Single-Line Emission Galaxies [PDF]
, 2007 We present two methods for determining spectroscopic redshifts of galaxies in the DEEP2 survey which display only one identifiable feature, an emission line, in the observed spectrum ("single-line galaxies").

Redshift clustering in the Hubble Deep Field [PDF]
, 1996 We present initial results from a redshift survey carried out with the Low Resolution Imaging Spectrograph on the 10~m W. M. Keck Telescope in the Hubble Deep Field.

Photometric redshifts: estimating their contamination and distribution using clustering information [PDF]
, 2010 We present a new technique to estimate the level of contamination between photometric redshift bins. If the true angular cross-correlation between redshift bins can be safely assumed to be zero, any measured cross-correlation is a result of contamination

, 2006 The DEIMOS spectrograph is nearing completion in the UC Lick shops and will be delivered to the Keck Observatory in 2001. Once it is operational, a team of astronomers will initiate DEEP2, a major redshift survey of galaxies that will consume approximately 120 nights at the Keck Observatory over a three year period.

Luminosity-Environment Relation in the Lowz Sample of the SDSS-III
Open Astronomy, 2016 In this work, we examine the environmental dependence of the u-, g-, r-, i- and z-band luminosities in the LOWZ sample of the Sloan Digital Sky Survey Data Release 10 (SDSS DR10).

z-GAL – A Comprehensive Redshift Survey of the Brightest Herschel Galaxies [PDF]
EPJ Web of Conferences, 2022 We here introduce z-GAL, a Large Program using NOEMA, aimed at a comprehensive 3 and 2-mm spectroscopic redshift survey of a large sample of 137 bright (S500μm > 80mJy) Herschel-selected high-z dusty star forming galaxies, probing the peak of cosmic ...

The Center for Astrophysics Redshift Survey [PDF]
Symposium - International Astronomical Union, 1983 We have completed the survey of radial velocities for all 2400 galaxies brighter than 14.5 at high galactic latitude in the northern hemisphere. This data set has already been used to derive a good measure of the local mean mass density, describe the overdensity and the dynamics of the local supercluster and to analyse the dynamics of groups and ...

European Physical Journal C: Particles and Fields, 2022 In this work, we discuss a new method to probe the redshift evolution of the gas depletion factor, i.e. the ratio by which the gas mass fraction of galaxy clusters is depleted with respect to the universal mean of baryon fraction.

Hydra — Centaurus: A Redshift Survey [PDF]
Symposium - 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.
