Peculiar velocity decomposition, redshift space distortion, and velocity reconstruction in redshift surveys: The methodology [PDF]

open access: yes, 2012
Massive spectroscopic surveys will measure the redshift space distortion (RSD) induced by galaxy peculiar velocity to unprecedented accuracy and open a new era of precision RSD cosmology.

A PUBLIC VOID CATALOG FROM THE SDSS DR7 GALAXY REDSHIFT SURVEYS BASED ON THE WATERSHED TRANSFORM [PDF]

open access: yes, 2012
We produce the most comprehensive public void catalog to date using the Sloan Digital Sky Survey Data Release 7 main sample out to redshift z = 0.2 and the luminous red galaxy sample out to z = 0.44.

GALAXY GROUPS IN THE 2MASS REDSHIFT SURVEY [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT A galaxy group catalog is constructed from the 2MASS Redshift Survey (2MRS) with the use of a halo-based group finder. The halo mass associated with a group is estimated using a “GAP” method based on the luminosity of the central galaxy and its gap with other member galaxies.

Constraining inflation with future galaxy redshift surveys [PDF]

open access: yes, 2012
With future galaxy surveys, a huge number of Fourier modes of the distribution of the large scale structures in the Universe will become available. These modes are complementary to those of the CMB and can be used to set constraints on models of the ...

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

Constraining cosmic expansion and gravity with galaxy redshift surveys [PDF]

open access: yes, 2012
We analyze the science reach of a next generation galaxy redshift survey such as BigBOSS to fit simultaneously for time varying dark energy equation of state and time- and scale-dependent gravity.

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 ...

Probing Dark Energy with Baryonic Acoustic Oscillations from Future Large Galaxy Redshift Surveys [PDF]

open access: yes, 2003
We show that the measurement of the baryonic acoustic oscillations in large high-redshift galaxy surveys offers a precision route to the measurement of dark energy.

The CNOC2 field galaxy redshift survey [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 1999
The CNOC2 field galaxy redshift survey is designed to provide measurements of the evolution of galaxies and their clustering over the redshift range 0 to 0.7. The sample is spread over four sky patches with a total area of about 1.5 square degrees. Here we report preliminary results based on two of the sky patches, and the redshift range of 0.15 to 0 ...
