摘要：

We show that the apparent redshift-space clustering of galaxies in the redshift range of 0.2-0.4 provides surprisingly useful constraints on dark-energy components in the Universe, because of the right balance between the density of objects and the survey depth. We apply Fisher matrix analysis to the luminous red galaxies in the Sloan Digital Sky Survey, as a concrete example. Possible degeneracies in the evolution of the equation of state and the other cosmological parameters are clarified.
