摘要
我们研究了星系团质量 与 Sunyaev-Zeldovich (SZ) 效应信号 之间的关系，样本包含 19 个天体，其弱引力透镜 (WL) 质量测量值源自 Subaru Telescope 数据并已见于文献。流体静力学 X 射线质量源自 XMM-Newton 档案数据，SZ 效应信号则测量自 Planck 全天巡天数据。我们发现 - 关系在斜率和归一化上与先前使用弱引力透镜质量的测定结果一致；然而，相对于基于流体静力学 X 射线质量代理关系的先前测量，存在归一化偏移。我们验证了我们的 SZ 效应测量结果与先前基于 Planck 数据的测定结果高度吻合。对于当前样本， 处的流体静力学 X 射线质量平均比相应的弱引力透镜质量大约 20%，这与预期相悖。我们表明，质量差异是由两种方法测得的质量集中度差异驱动的，且对于当前样本，这种质量差异和质量集中度的差异在受扰动系统中尤为显著。质量差异还与 X 射线和弱引力透镜分析中所用中心的偏移有关，这一点在受扰动系统中同样最为重要。我们概述了为实现 X 射线和弱引力透镜观测在星系团质量测量上达成一致所需的几种方法。
