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 $S_8=σ_8 \sqrt{Ω_{\rm m}/0.3}$ 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.

High $H_0$ Values from CMB E-mode Data: A Clue for Resolving the Hubble Tension?
由普朗克、ACTPol和SPTPol测量的E模式（EE）CMB功率谱将哈勃常数约束为标准$Λ$ CDM模型（后验均值和中心68%区间界限）内的$70.0\pm2.7$、$72.4^{+3.9}_{-4.8}$和$73.1^{+3.3}_{-3.9}$ km s $^{-1}$ Mpc $^{-1}$。这些值高于普朗克温度（TT）功率谱的限制，并与造父变星超新星距离阶梯测量$H_0=73.2\pm1.3$ km s $^{-1}$ Mpc $^{-1}$一致。如果这种对更高值的偏好在联合分析中得到加强，它可能会为哈勃分歧的解决提供一个有趣的暗示。然而，我们发现，结合普朗克，ACTPol，和SPTPol EE的可能性产生$H_0=68.7\pm1.3$ km s $^{-1}$ Mpc $^{-1}$，$2.4σ$低于距离阶梯测量。这是由于不同的简并方向在整个参数空间，特别是涉及重子密度，$Ω_bh^2$，和标量倾斜，$n_s$，所产生的灵敏度不同的多极范围。我们表明，E-模式$Λ$ CDM约束是一致的，在$1.4σ$内的不同实验，并与普朗克TT结果在$0.8σ$。结合普朗克，ACTPol，和SPTPol EE数据约束的现象学透镜振幅，$A_L=0.89\pm0.10$，与预期值一致的单位。
Multichroic TES Bolometers and Galaxy Cluster Mass Scaling Relations with the South Pole Telescope
南极望远镜（英语：South Pole Telescope）是一个高分辨率的微波频率望远镜，用于观测宇宙微波背景（CMB）。到目前为止，已经在SPT上安装了两台摄像机，对CMB进行了两次调查，第一次是强度调查（SPT-SZ），第二次是强度和偏振调查（SPTpol）。目前正在开发第三代偏振敏感相机（SPT-3G）。本论文介绍了工作跨越所有三个仪器上的SPT。我提出我的工作在时间颠倒的顺序，遵循仪器开发，部署和分析的规范叙述。首先，新的3波段多色过渡边缘传感器（TES）的SPT-3G实验测辐射热计的开发和测试进行了详细说明，其次是频率复用低温读出电子的SPTpol实验的开发和部署，并得出结论与SPT-SZ仪器所采取的数据分析。我描述了一个贝叶斯似然为基础的方法，我开发的测量综合康普顿化（YSZ）的星系团的Sunyaev-Zel 'dovich（SZ）效应，并限制星系团YSZ质量标度关系的发展。
