We measure the correlation of galaxy lensing and cosmic microwave background lensing with a set of galaxies expected to trace the matter density field. The measurements are performed using pre-survey Dark Energy Survey (DES) Science Verification optical imaging data and millimeter-wave data from the 2500 square degree South Pole Telescope Sunyaev-Zel'dovich (SPT-SZ) survey. The two lensing-galaxy correlations are jointly fit to extract constraints on cosmological parameters, constraints on the redshift distribution of the lens galaxies, and constraints on the absolute shear calibration of DES galaxy lensing measurements. We show that an attractive feature of these fits is that they are fairly insensitive to the clustering bias of the galaxies used as matter tracers. The measurement presented in this work confirms that DES and SPT data are consistent with each other and with the currently favored $Λ$CDM cosmological model. It also demonstrates that joint lensing-galaxy correlation measurement considered here contains a wealth of information that can be extracted using current and future surveys.

Sunyaev-Zel'dovich Effect and X-ray Scaling Relations from Weak-Lensing Mass Calibration of 32 SPT Selected Galaxy Clusters
质量可观测标度关系的不确定性是目前基于星系团的宇宙学的限制因素。弱引力透镜可以提供直接的质量校准并减小质量不确定性。我们提出了新的地基弱透镜观测的19个南极望远镜(SPT)选定的星系团在红移$0.29 \leq z \leq 0.61$,并将它们与以前报道的空间观测的13个星系团在红移$0.576 \leq z \leq 1.132$约束与Sunyaev-Zel'dovich效应(SZE),集群气体质量\mgas,\yx,\mgas \和X射线温度的产品的集群质量标度关系。我们扩展了以前使用的尺度关系和宇宙学约束的分析框架,从SPT选择集群利用弱透镜信息。本文介绍了一种新的方法来估计背景星系的有效平均红移分布,并量化了一些影响弱透镜模型的系统误差。这些误差包括使用$N$体模拟将Navarro-Frenk-White剖面拟合到减小的剪切而引起的偏差的校准。我们对分析进行盲化以避免确认偏差。我们能够将系统的不确定性限制在5.6%的集群质量(68%的置信度)。我们对质量-X射线可观测的标度关系参数的约束与早期研究所获得的一致,我们对质量-SZE标度关系的约束与最近SPT-SZ宇宙学分析中使用的基于模拟的先验一致。我们现在可以取代外部质量校准先验使用在以前的SPT-SZ宇宙学研究与直接,内部校准获得相同的集群。

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。
