我们分析了斯隆数字巡天III重子振荡光谱巡天（BOSS）数据发布9（DR 9）样本中大质量星系的各向异性聚类，该样本由264283个星系组成，红移范围为0.43 - 0.57，合并后意味着ΩΛ = 0.74 ± 0.016，与z < 0.57的宇宙演化无关。所有这些约束都假设了与尺度无关的线性增长，并假设广义相对论来计算（10%）非线性模型修正和我们的误差。在我们的配套论文中，Samushia等人，我们将进一步探讨这些观测结果的宇宙学意义。
We analyse the anisotropic clustering of massive galaxies from the Sloan Digital Sky Survey III Baryon Oscillation Spectroscopic Survey (BOSS) Data Release 9 (DR9) sample, which consists of 264 283 galaxies in the redshift range 0.43 0.57, and when combined imply ΩΛ = 0.74 ± 0.016, independent of the Universe's evolution at z < 0.57. All of these constraints assume scale-independent linear growth, and assume general relativity to compute both (10 per cent) non-linear model corrections and our errors. In our companion paper, Samushia et al., we explore further cosmological implications of these observations.
