11 Jul 2016 | | Abstract: | We investigate the anisotropic clustering of the Baryon Oscillation
Spectroscopic Survey (BOSS) Data Release 12 (DR12) sample, which consists of
$1,198,006$ galaxies in the redshift range $0.2 < z < 0.75$ and a sky
coverage of $10,252,$deg$^2$. We analyse this dataset in Fourier space, using
the power spectrum multipoles to measure Redshift-Space Distortions (RSD)
simultaneously with the Alcock-Paczynski (AP) effect and the Baryon Acoustic
Oscillation (BAO) scale. We include the power spectrum monopole, quadrupole and
hexadecapole in our analysis and compare our measurements with a perturbation
theory based model, while properly accounting for the survey window function.
To evaluate the reliability of our analysis pipeline we participate in a mock
challenge, which resulted in systematic uncertainties significantly smaller
than the statistical uncertainties. While the high-redshift constraint on
$fsigma_8$ at $z_{
m eff}=0.61$ indicates a small ($sim 1.4sigma$)
deviation from the prediction of the Planck $Lambda$CDM model, the
low-redshift constraint is in good agreement with Planck $Lambda$CDM. This
paper is part of a set that analyses the final galaxy clustering dataset from
BOSS. The measurements and likelihoods presented here are combined with others
in~citet{Alam2016} to produce the final cosmological constraints from BOSS. | | Source: | arXiv, 1607.3150 | | Services: | Forum | Review | PDF | Favorites | |
