The AAO 2DF QSO Redshift Survey [PDF]
Symposium - International Astronomical Union, 1999 The study of large-scale structure through QSO clustering provides a potentially powerful route to determining the fundamental cosmological parameters of the Universe (see Croom & Shanks 1996). Unfortunately, previous QSO clustering studies have been limited by the relatively small sizes of homogeneous QSO catalogues that have been available ...

Cosmology with clustering anisotropies: disentangling dynamic and geometric distortions in galaxy redshift surveys [PDF]
, 2012 We investigate the impact of different observational effects affecting a precise and accurate measurement of the growth rate of fluctuations from the anisotropy of clustering in galaxy redshift surveys.

Towards more realistic forecasting of dark energy constraints from galaxy redshift surveys [PDF]
, 2012 Galaxy redshift surveys are becoming increasingly important as a dark energy probe. We improve the forecasting of dark energy constraints from galaxy redshift surveys by using the ‘dewiggled’ galaxy power spectrum, P_(dw)(k), in the Fisher matrix ...

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

Constraining inflation with future galaxy redshift surveys [PDF]
, 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 ...

GALAXY GROUPS IN THE 2MASS REDSHIFT SURVEY [PDF]
The 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 cosmic expansion and gravity with galaxy redshift surveys [PDF]
, 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.

Growth factor and galaxy bias from future redshift surveys: a study on parametrizations [PDF]
, 2011 Many experiments in the near future will test dark energy through its effects on the linear growth of matter perturbations. In this paper, we discuss the constraints that future large-scale redshift surveys can put on three different parametrizations of ...
