Probing dark energy with the shear-ratio geometric test
We adapt the Jain–Taylor (2003) shear-ratio geometric lensing method to measure the dark energy equation of state, w = pv/ρv and its time derivative from dark matter haloes in cosmologies with arbitrary spatial curvature. The full shear-ratio covariance matrix is calculated for lensed sources, including the intervening large-scale structure and photometric redshift errors as additional sources ...
متن کاملProbing Dark Energy with Snap
The distance-redshift relation observed for supernovae has led to the discovery that the expansion of the universe is accelerating. A next generation experiment, the Supernova/Acceleration Probe (SNAP), can investigate the nature of the dark energy responsible, determining its energy density contribution and equation of state. In addition, indications of time variation in the equation of state ...
متن کاملProbing dark energy with future surveys
I review the observational prospects to constrain the equation of state parameter of dark energy and I discuss the potential of future imaging and redshift surveys. Bayesian model selection is used to address the question of the level of accuracy on the equation of state parameter that is required before explanations alternative to a cosmological constant become very implausible. I discuss resu...
متن کاملProbing Neutrino Dark Energy with Extremely High-Energy Cosmic Neutrinos
Recently, a new non-Standard Model neutrino interaction mediated by a light scalar field was proposed, which renders the big-bang relic neutrinos of the cosmic neutrino background a natural dark energy candidate, the so-called Neutrino Dark Energy. As a further consequence of this interaction, the neutrino masses become functions of the neutrino energy densities and are thus promoted to dynamic...
متن کاملProbing the dark energy with redshift space quasar clustering distortion
We have run Monte Carlo simulations, for quasar clustering redshift distortions in the Two-Degree Field QSO Redshift Survey (2QZ), in order to elicit the power of redshift distortions (geometric Alcock-Paczyński and linear kinematic) to constrain the cosmological density and equation of state parameters, Ωm0,Ωx0, w, of a pressureless matter + dark energy model. It turns out that, for the cosmol...
