Abstract

The expected degree of constraints on dark-energy models from intermediate-redshift galaxies such as luminous red galaxies (LRGs) was predicted for the first time. It was shown that Ω_Q0 and w_eff can be constrained well. Furthermore, it was demonstrated that the prior input of the curvature and Hubble's constant are important to reduce the bounds on the dark-energy density, but not so important on the EOS parameters.
