我们使用重子振荡光谱巡天数据发布12（BOSS DR 12）的组合样本测量的两点星系相关函数进行层析重子声振荡（BAOs）分析，该样本覆盖了0.2 < z < 0.75的红移范围。在将样本分割成多个重叠的红移切片以提取星系团的红移信息后，利用MultiDark-Patchy模拟星表校准的全协方差矩阵，我们获得了9个有效红移处的D-A（z）/r（d）和H（z）r（d）测量值。利用重建的星系表，我们获得了D-A（z）/r（d）的精度为1.3- 2.2%，H（z）r（d）的精度为2.1- 6.0%。为了量化来自层析成像信息的增益，我们使用我们的九仓BAO测量、共识三仓BAO和Alam等人在三个有效红移处的红移空间失真测量来比较宇宙学参数的约束，以及在单个有效红移处的非层析成像（单箱）BAO测量。将9个仓约束结果与1个仓约束结果进行比较，对于状态方程参数w（DE）的Chevallier-Polarski-Linder参数化，可以将暗能量品质因数提高1.24倍。与三箱约束结果相比，来自九箱约束的w（0）和w（a）的误差略有改善。
We perform a tomographic baryon acoustic oscillations (BAOs) analysis using the two-point galaxy correlation function measured from the combined sample of Baryon Oscillation Spectroscopic Survey Data Release 12 (BOSS DR12), which covers the redshift range of 0.2 < z < 0.75. Upon splitting the sample into multiple overlapping redshift slices to extract the redshift information of galaxy clustering, we obtain a measurement of D-A(z)/r(d) and H(z)r(d) at nine effective redshifts with the full covariance matrix calibrated using MultiDark-Patchy mock catalogues. Using the reconstructed galaxy catalogues, we obtain the precision of 1.3-2.2 per cent for D-A(z)/r(d) and 2.1-6.0 per cent for H(z)r(d.) To quantify the gain from the tomographic information, we compare the constraints on the cosmological parameters using our nine-bin BAO measurements, the consensus three-bin BAO and redshift space distortion measurements at three effective redshifts in Alam et al., and the non-tomographic (one-bin) BAO measurement at a single effective redshift. Comparing the nine-bin with one-bin constraint result, it can improve the dark energy Figure of Merit by a factor of 1.24 for the Chevallier-Polarski-Linder parametrization for equation-of-state parameter w(DE). The errors of w(0) and w(a) from nine-bin constraints are slightly improved when compared to the three-bin constraint result.
