BOSS Publications and Results

BOSS overview paper

The motivation for BOSS and an overview of target selection, survey design, and observing strategy are described in Dawson et al. 2013, The Baryon Oscillation Spectroscopic Survey of SDSS-III, published in the January 2013 issue of Astronomical Journal. A preprint-style PDF of the paper is available on this site.

DR9 Galaxy Clustering Science results presented in BOSS publications

Below we list measurements, covariance matrices and analysis tools that have been presented and utilized in BOSS DR9 galaxy clustering papers. The covariance matrices for all measurements are calculated from the 600 mock DR9 CMASS realizations, created using PTHalos, described in Manera et al. (2013). Please cite this paper if the errors are used in any analysis.

• CMASS DR9 results of clustering wedges from: Kazin, Sánchez et al. (2013). Also featured in Anderson et al. (2013) (anisotropic clustering results) and Sánchez, Kazin et al. (2013).

  • A tarball of the posteriors of H(z) and D_A(z), clustering wedges measurements and covariance matrices (and their inverses). All results are both for pre- and post-reconstruction.
