We present thermal Sunyaev-Zel'dovich (tSZ) Compton-$y$ parameter maps constructed from two years (2019-2020) of observations with the South Pole Telescope (SPT) third-generation camera, SPT-3G, combined with data from the Planck satellite. Using a linear combination (LC) pipeline, we obtain a suite of reconstructions that explore different trade-offs between statistical sensitivity and suppression of astrophysical contaminants, including minimum-variance, CMB-deprojected, and CIB-deprojected $y$-maps. We validate these maps through different statistical techniques such as auto- and cross-power spectra with large-scale structure tracers as well as stacking on cluster locations. These tests are used to understand the balance between noise and astrophysical foreground residuals (such as the CIB) in combination with the recovery of the tSZ signal for different maps. For example, results from stacking at the location of clusters confirm the robustness of the recovered tSZ signal over the $\sim 1500\: {\rm deg}^2$ SPT-3G survey field used in this analysis. The high-resolution and low-noise maps produced here provide an important cosmological tool for future studies, including measurements of the Compton-$y$ map power spectrum, cross-correlations with other tracers of the large-scale structure, detailed modeling of cluster pressure profiles, and study of the thermodynamic state of the baryons in the Universe.

Constraints on Pre-Recombination Early Dark Energy from SPT-3G Public Data
早期的暗能量(EDE)是一种针对哈勃张力的解决方案,其中一个新的宇宙学场在复合之前加速宇宙膨胀,并减小声音视界的物理尺寸。在以前的工作中,在最新的阿塔卡玛宇宙望远镜数据(ACT DR 4)中发现了对非零EDE贡献的轻微偏好,而普朗克卫星遗留数据本身并没有显示出证据。我们发现,在目前的精度水平的SPT-3G,EDE的贡献,宇宙的总能量密度之前的重组$\sim 10\%$不能被排除,但数据也是一致的,没有EDE。ACT DR 4和SPT-3G与普朗克大尺度温度各向异性测量的组合显示了非零EDE的提示($2.6σ$);然而,当包括完整的普朗克2018数据集时,这种偏好消失了。
Weak lensing analysis of SZ-selected clusters of galaxies from the SPT and Planck surveys
我们提出了弱透镜分析的宽视场成像仪SZ星系团(WISCy)的样本,一组12星系团的选择,他们的Sunyaev-Zel'dovich(SZ)效应。在开发新的和改进的方法,从绝对多波段光度学在集群领域的背景选择和确定几何透镜尺度因子,我们比较弱透镜质量估计与公共X射线和SZ数据。我们发现与流体静力学X射线质量的一致性,没有显著的偏差,没有质量依赖的偏差和小于20%的固有散射和约束fgas,500 c =0.128+0.029-0.023。我们独立校准南极望远镜的意义质量关系,并找到与以前的结果一致。弱透镜质量和普朗克康普顿参数的比较,无论是提取自相一致的质量可观测关系(MOR)或使用X射线先验信息的集群大小,显示出显着的差异。对MOR的偏离与星系团的质量和红移密切相关。这可以通过比预期的康普顿减量相对于质量的斜率明显更浅以及先前基于X射线的质量校准中的相应问题来解释,或者通过SZ信号提取中的尺寸或红移依赖性偏差来解释。

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。
