We present the results obtained from the full-shape cosmology analysis of the redshift-space power spectra for 4 galaxy samples of the SDSS-III BOSS DR12 galaxy catalog over 0 . 2 < z < 0 . 75. For the theoretical template, we use an emulator that was built from an ensemble set of N -body simulations, which enables fast and accurate computation of the redshift-space power spectrum of “halos”. Combining with the halo occupation distribution to model the galaxy-halo connection, we can compute the…
