ON THE RECOVERY OF THE LOCAL GROUP MOTION FROM GALAXY REDSHIFT SURVEYS [PDF]

open access: yes, 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]

open access: yes, 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]

open access: yes, 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 ...

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

Cosmology with clustering anisotropies: disentangling dynamic and geometric distortions in galaxy redshift surveys [PDF]

open access: yes, 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]

open access: yes, 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 ...

The Las Campanas Redshift Survey [PDF]

open access: yesThe Astrophysical Journal, 1996
The Las Campanas Redshift Survey (LCRS) consists of 26418 redshifts of galaxies selected from a CCD-based catalog obtained in the $R$ band. The survey covers over 700 square degrees in 6 strips, each 1.5$\arcdeg$ x 80$\arcdeg$, three each in the North and South galactic caps. The median redshift in the survey is about 30000 km~s$^{-1}$.
