Measuring galaxy [OII] emission line doublet with future ground-based wide-field spectroscopic surveys [PDF]
The next generation of wide-field spectroscopic redshift surveys will map the large-scale galaxy distribution in the redshift range 0.7 ...

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

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

Growth factor and galaxy bias from future redshift surveys: a study on parametrizations [PDF]
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 ...

Measuring Redshift-Space Distortions using Photometric Surveys [PDF]
We outline how redshift-space distortions (RSD) can be measured from the angular correlation function w({\theta}), of galaxies selected from photometric surveys.

Combining weak-lensing tomography and spectroscopic redshift surveys [PDF]
Redshift space distortion (RSD) is a powerful way of measuring the growth of structure and testing General Relativity, but it is limited by cosmic variance and the degeneracy between galaxy bias b and the growth rate factor f.

Cosmology with large redshift surveys
Galaxy redshift surveys are a major tool to address the most challenging cosmological problems facing cosmology, like the nature of dark energy and properties dark matter.

Measuring the cosmological constant with redshift surveys [PDF]
It has been proposed that the cosmological constant $\Lambda$ might be measured from geometric effects on large-scale structure. A positive vacuum density leads to correlation-function contours which are squashed in the radial direction when calculated ...

A NEW METHOD FOR THE DETERMINATION OF THE GROWTH RATE FROM GALAXY REDSHIFT SURVEYS [PDF]
Given a redshift survey of galaxies with measurements of apparent magnitudes, we present a novel method for measuring the growth rate f(Ω) of cosmological linear perturbations.
