Galaxy Clustering and Dark Energy
We study the evolution of galaxy clustering in various cosmological models with quintessence. We investigate how the analytical predictions vary with change of dark energy equation of state wX . Comparing these predictions against available data we test the possibility of constraining the equation of state with future galaxy surveys and to what extent the problems of galaxy bias can be modelled...
متن کاملCan a galaxy redshift survey measure dark energy clustering?
A wide-field galaxy redshift survey allows one to probe galaxy clustering at largest spatial scales, which carries invaluable information on horizon-scale physics complementarily to the cosmic microwave background (CMB). Assuming the planned survey consisting of z ∼ 1 and z ∼ 3 surveys with areas of 2000 and 300 deg, respectively, we study the prospects for probing dark energy clustering from t...
متن کاملMeasuring neutrino masses and dark energy with weak lensing tomography
Surveys of weak gravitational lensing of distant galaxies will be one of the key cosmological probes in the future. We study the ability of such surveys to constrain neutrino masses and the equation of state parameter of the dark energy, focussing on how tomographic information can improve the sensitivity to these parameters. We also provide a detailed discussion of systematic effects pertinent...
متن کاملOn the Determination of Neutrino Masses and Dark Energy Evolution
We discuss the possibilities of the simultaneous determination of the neutrino masses and the evolution of dark energy from future cosmological observations such as cosmic microwave background (CMB), large scale structure (LSS) and the cross correlation between them. Recently it has been discussed that there is a degeneracy between the neutrino masses and the equation of state for dark energy. ...
متن کاملNeutrino Masses from Cosmological Probes in Interacting Neutrino Dark-Energy Models
We investigate whether interaction between massive neutrinos and quintessence scalar field is the origin of the late time accelerated expansion of the universe. We present explicit formulas of the cosmological linear perturbation theory in the neutrinos probes of dark-energy model, and calculate cosmic microwave background anisotropies and matter power spectra. In these models, the evolution of...
