摘要
我们给出了MaxBCG星系团目录的苏尼亚耶夫-泽尔多维奇(SZ)信号-富度标度关系(Y500-N200)。通过在普朗克全天图上应用多频匹配滤波器，我们根据弱引力透镜校准的质量-富度关系(N200-M500)调整滤波器，测量了每个星系团的SZ信号。我们对单个测量值进行分箱，并以高显著性检测到最低富度系统(N200=10)的SZ信号，在质量低至M500~5e13 Msolar的系统中实现了SZ信号的探测。观测到的Y500-N200关系在整个富度范围内可以很好地用幂律模型描述。在给定N200下，其归一化低于基于X射线模型和已发表的质量-富度关系的预测。然而，一个X射线子样本确实符合预测的标度关系，并且模型预测确实再现了我们测量的箱平均SZ信号与箱平均X射线光度之间的关系。在固定富度下，我们发现Y500-N200关系的内在弥散为60%，在低富度时上升至约100%。得益于其全天覆盖，普朗克提供了超过13,000个MaxBCG星系团的观测数据，以及前所未有的SZ/光学数据集，将已知的星系团标度律列表扩展至包括SZ-光学特性。该数据集为星系形成模型提供了重要线索。此外，由观测到的SZ-富度标度关系所隐含的SZ-质量关系的较低归一化，对星系团物理学和利用SZ星系团进行的宇宙学研究具有重要意义。
