摘要
我们利用 SDSS-III 重子振荡光谱巡天（Baryon Oscillation Spectroscopic Survey）数据发布 11（Data Release 11）中超过 164,000 个类星体，测量了类星体与 Lyman alpha 森林吸收的大尺度互相关。我们将之前基于数据发布 9 中约 60,000 个类星体的研究扩展到了更大的分离距离，从而得以测量沿视线方向的重子声学振荡（BAO）尺度 以及垂直于视线方向的尺度 ，这与宇宙微波背景辐射（CMB）及其他 BAO 数据一致。使用来自 Planck 数据的声视界最佳拟合值（），我们可以将这些结果转化为对哈勃参数 和角直径距离 的测量。测量得到的互相关函数以及用于拟合 BAO 尺度的代码更新版本（baofit）已公开提供。
