星系位置测量、星系透镜和宇宙微波背景透镜(CMB)测量之间的交叉关联的联合分析为宇宙的大尺度结构提供了强大的约束。在即将到来的分析中，我们将通过使用暗能量调查(DES)的第三年数据以及南极望远镜(SPT)和普朗克的CMB数据测量的这种交叉关联的分析，给出宇宙学上的限制。在这里，我们介绍了这一分析的两个关键部分：(1)SPT-SZ调查足迹中改进的CMB透镜图，以及(2)将用于从互相关测量中提取宇宙学信息的分析方法。相对于之前从相同的CMB观测中制作的透镜图，我们已经实施了消除热Sunyaev Zel‘dovich效应污染的技术，使得能够从比之前使用DES第一年数据分析的互相关测量更小的角度尺度提取宇宙学信息。我们描述了这些映射和DES数据之间的交叉关联模型，并验证了我们的建模选择，以证明我们分析的健壮性。然后，我们预测了来自星系调查的预期宇宙学约束-CMB透镜自关联和交叉关联。我们发现星系-CMB透镜关联和星系剪切-CMB透镜关联本身将在几个百分比水平上对$S_8=\sigma_8\Sqrt{\Omega_{\rmm}/0.3}$起到约束作用，为Des-Only约束提供了强有力的一致性检验。我们探索了去除剪切校准的外部先验的情况，发现CMB透镜互相关的联合分析可以在5%到10%的水平上对剪切校准幅度提供约束。
Joint analyses of cross-correlations between measurements of galaxy positions, galaxy lensing, and lensing of the cosmic microwave background (CMB) offer powerful constraints on the large-scale structure of the Universe. In a forthcoming analysis, we will present cosmological constraints from the analysis of such cross-correlations measured using Year 3 data from the Dark Energy Survey (DES), and CMB data from the South Pole Telescope (SPT) and Planck. Here we present two key ingredients of this analysis: (1) an improved CMB lensing map in the SPT-SZ survey footprint, and (2) the analysis methodology that will be used to extract cosmological information from the cross-correlation measurements. Relative to previous lensing maps made from the same CMB observations, we have implemented techniques to remove contamination from the thermal Sunyaev Zel'dovich effect, enabling the extraction of cosmological information from smaller angular scales of the cross-correlation measurements than in previous analyses with DES Year 1 data. We describe our model for the cross-correlations between these maps and DES data, and validate our modeling choices to demonstrate the robustness of our analysis. We then forecast the expected cosmological constraints from the galaxy survey-CMB lensing auto and cross-correlations. We find that the galaxy-CMB lensing and galaxy shear-CMB lensing correlations will on their own provide a constraint on $S_8=\sigma_8 \sqrt{\Omega_{\rm m}/0.3}$ at the few percent level, providing a powerful consistency check for the DES-only constraints. We explore scenarios where external priors on shear calibration are removed, finding that the joint analysis of CMB lensing cross-correlations can provide constraints on the shear calibration amplitude at the 5 to 10% level.
