The 2Mass Redshift Survey [PDF]
Highlights 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.

COMPARING DENSE GALAXY CLUSTER REDSHIFT SURVEYS WITH WEAK-LENSING MAPS [PDF]
, 2014 We use dense redshift surveys of nine galaxy clusters at z ∼ 0.2 to compare the galaxy distribution in each system with the projected matter distribution from weak lensing.

ON THE RECOVERY OF THE LOCAL GROUP MOTION FROM GALAXY REDSHIFT SURVEYS [PDF]
, 2014 There is an ∼150 km s−1 discrepancy between the measured motion of the Local Group (LG) of galaxies with respect to the cosmic microwave background and the linear theory prediction based on the gravitational force field of the large-scale structure in ...

Peculiar velocity decomposition, redshift space distortion, and velocity reconstruction in redshift surveys. II. Dark matter velocity statistics [PDF]
, 2013 Massive spectroscopic redshift surveys open a promising window to accurately measure peculiar velocity at cosmological distances through redshift space distortion (RSD). In Paper I Zhang et al. [Phys. Rev.

Measuring the transition to homogeneity with photometric redshift surveys [PDF]
, 2013 We study the possibility of detecting the transition to homogeneity using photometric redshift catalogs. Our method is based on measuring the fractality of the projected galaxy distribution, using angular distances, and relies only on observable ...

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 ...

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.

Spectral Templates from Multicolor Redshift Surveys [PDF]
, 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.
