Constraints on dark energy from the lookback time versus redshift test
We use lookback time versus redshift data from galaxy clusters (Capozziello et al. 2004) and passively evolving galaxies (Simon et al. 2005), in combination with the WMAP determination of the age of the Universe, to constrain dark energy cosmological model parameters. Current lookback time data provide interesting and moderately restrictive constraints on cosmological parameters. When used join...

متن کاملEntropy Bounds and Dark Energy
Entropy bounds render quantum corrections to the cosmological constant Λ finite. Under certain assumptions, the natural value of Λ is of order the observed dark energy density ∼ 10 −10 eV 4 , thereby resolving the cosmological constant problem. We note that the dark energy equation of state in these scenarios is w ≡ p/ρ = 0 over cosmo-logical distances, and is strongly disfavored by observation...
متن کاملQuasar clustering redshift distortion constraints on dark energy
Redshift distortions, both geometrical and kinematical, of quasar clustering are simulated, for the Two-Degree Field QSO Redshift Survey (2QZ), showing that they are very effective to constrain the cos-mological density and equation of state parameters, Ω m0 , Ω x0 and w. Particularly, it emerges that, for the cosmological constant case, the test is especially sensitive to the difference Ω m0 −...
متن کاملDark energy reflections in the redshift-space quadrupole.
We show that the redshift-space quadrupole will be a powerful tool for constraining dark energy even if the baryon oscillations are missing from the monopole power spectrum and bias is scale and time dependent. We calculate the accuracy with which next-generation galaxy surveys such as KAOS will measure the quadrupole power spectrum, which gives the leading anisotropies in the power spectrum in...
