Descripción
We perform a tomographic structure growth and expansion rate analysis
using the monopole, quadrupole and hexadecapole of the redshift-space
galaxy power spectrum derived from the Sloan Digital Sky Survey
(SDSS-III) Baryon Oscillation Spectroscopic Survey (BOSS) Data Release
12 combined sample, which covers the redshift range of 0.20 < z <
0.75. By allowing for overlap between neighbouring redshift slices in
order to extract information on the light-cone, we successfully obtain
joint BAO and RSD constraints with a precision of 2-3 per cent for
DA, 3-10 per cent for H and 9-12 per cent for
fσ8 with a redshift resolution of Δz ˜
0.04. Our measurement is consistent with that presented in Wang et al.,
where the analysis is performed in configuration space. We apply our
measurement to constrain the f(R) gravity model, and find that the 95
per cent CL upper limit of log10B0 can be reduced
by 11 per cent by our tomographic BAO and RSD measurements. We make our
joint BAO and RSD measurements publicly available at
