Testing general relativity with the multipole spectra of the SDSS luminous red galaxies

As a test of general relativity on cosmological scales, we measure the γ parameter for the growth rate of density perturbations using the redshift-space distortion of the luminous red galaxies in the Sloan Digital Sky Survey (SDSS). Assuming the cosmological constant model, which matches the results of the WMAP experiment, we find γ = 0.51 +1.3(σ8 − 0.8)± 0… (More)
