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.

The SSA22 H i Tomography Survey (SSA22-HIT). I. Data Set and Compiled Redshift Catalog

open access: yesThe Astronomical Journal, 2023
We conducted a deep spectroscopic survey, named SSA22-HIT, in the SSA22 field with the DEep Imaging MultiObject Spectrograph (DEIMOS) on the Keck telescope, designed to tomographically map high- z H i gas through analysis of Ly α absorption in background

The 2Mass Redshift Survey [PDF]

open access: yesHighlights of Astronomy, 1998
With the current convergence of determinations of the Hubble Constant (e.g. The Extragalactic Distance Scale, 1997, Livio, Donahue and Panagia, eds.) to values within ±25% rather than a factor of two, and the clear possibility of determining q0 using high redshift supernovae (Garnavich et al.

Spectral Templates from Multicolor Redshift Surveys [PDF]

open access: yes, 1999
Understanding how the physical properties of galaxies (e.g. their spectral type or age) evolve as a function of redshift relies on having an accurate representation of galaxy spectral energy distributions.

The effects of spatial resolution on Integral Field Spectrograph surveys at different redshifts. The CALIFA perspective [PDF]

open access: yes, 2013
Over the past decade, 3D optical spectroscopy has become the preferred tool for understanding the properties of galaxies and is now increasingly used to carry out galaxy surveys. Low redshift surveys include SAURON, DiskMass, ATLAS3D, PINGS and VENGA. At

Bayesian inference from photometric redshift surveys [PDF]

open access: yes, 2011
We show how to enhance the redshift accuracy of surveys consisting of tracers with highly uncertain positions along the line of sight. Photometric surveys with redshift uncertainty delta_z ~ 0.03 can yield final redshift uncertainties of delta_z_f ~ 0 ...

A Redshift Survey of IRAS Galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1988
We have completed a redshift survey of approximately 2200 IRAS galaxies, flux limited at 60μ. The survey covers 76% of the sky and has a characteristic depth of ≈ 6000 km s−1, making it ideal for large scale structure studies requiring whole sky coverage.

Optical Redshift Surveys [PDF]

open access: yesHighlights of Astronomy, 1992
Redshift surveys of galaxies have been over the past decade the major source of information for studies of the large-scale structure of the Universe. Following the completion of the original CfA Redshift Survey, several groups have joined the endeavor, probing different regions of the sky to different depths in a remarkable long-term effort to study ...

The density and peculiar velocity fields of nearby galaxies [PDF]

open access: yes, 1995
We review the quantitative science that can be and has been done with redshift and peculiar velocity surveys of galaxies in the nearby universe. After a brief background setting the cosmological context for this work, the first part of this review ...
