英文摘要We perform an anisotropic clustering analysis of 1,133,326 galaxies from the Sloan Digital Sky Survey (SDSS-III) Baryon Oscillation Spectroscopic Survey Data Release 12 covering the redshift range 0.15 < z < 0.69. The geometrical distortions of the galaxy positions, caused by incorrect assumptions in the cosmological model, are captured in the anisotropic two-point correlation function on scales of 6-40 h(-1) Mpc. The redshift evolution of this anisotropic clustering is used to place constraints on the cosmological parameters. We improve the methodology of Li et al. to enable efficient exploration of high-dimensional cosmological parameter spaces, and apply it to the Chevallier-Polarski-Linder parameterization of dark energy, w = w(0) + w(a)z/(1 + z). In combination with data on the cosmic microwave background, baryon acoustic oscillations, Type Ia supernovae, and H-0 from Cepheids, we obtain Omega(m) = 0.301 +/- 0.008, w(0) = -1.042 +/- 0.067, and w(a) = -0.07 +/- 0.29 (68.3% CL). Adding our new Alcock-Paczynski measurements to the aforementioned results reduces the error bars by similar to 30%-40% and improves the dark-energy figure of merit by a factor of similar to 2. We check the robustness of the results using realistic mock galaxy catalogs.
