摘要
我们利用所有可用的重子声学振荡距离测量与哈勃参数数据，在简单宇宙学模型中约束宇宙学常数 、动力学暗能量与空间曲率。我们发现共识性的空间平坦 CDM 模型对数据提供了合理拟合，但取决于哈勃常数先验与宇宙学模型，它可偏离最佳拟合模型略多于 1，而后者可偏好温和的暗能量动力学或非平坦空间超曲面。

备注
This version is a revision of the original, the results of which were mistaken due to a recurrent typo in the Python codes we used to analyze the data. Figures 1-3 and tables 3-6 have been updated, in addition to the abstract, section 5, and section 6. Minor revisions have been made elsewhere in the text in accordance with referee comments.
