SPT-3G CMB 引力透镜对 DES Year-3 星团质量校准
摘要
我们测量了暗能量探测器 Year-3 红马帕尔(redMaPPer)星团样本中星团方向上的堆叠引力信号，利用来自南极望远镜(SPT)第三代 CMB 相机(SPT-3G)的 CMB 温度数据。我们使用由 SPT-3G 'Main' 调查初始 2 年数据构建的温度图估计引力信号，覆盖南天 1500 平方度。随后将该信号作为 DES 样本平均星团质量的代理。本工作中，我们采用了三个版本的红马帕尔目录：包含 8865 个星团的 Flux-Limited 样本、包含 5391 个星团的 Volume-Limited 样本，以及包含 4450 个星团的 Volume&Redshift-Limited 样本。对于这三个样本，我们发现平均星团质量分别为 [stat.] [sys.], [stat.] [sys.]，以及 [stat.] [sys.]。这一结果相较于前几代 SPT 调查中使用 CMB 星团引力透镜进行测量以及目前最严格的 CMB 星团引力透镜质量测量，提高了约约 2 倍的精度。总体而言，我们的结果与先前工作中基于 CMB 星团引力透镜、光学弱引力和速度分布测量（来自 DES、SDSS 和 Planck 数据的组合）校准的红马帕尔质量-丰度关系一致，未见显著矛盾。我们随后将样本划分为 3 个红度 bin 和 3 个丰度 bin，发现这些 bin 中也未见与光学弱引力校准质量之间的显著矛盾。我们预测在使用两者（温度和偏挝数据）以及包含约 1400 平方度 'Extended' SPT-3G 调查观测后，完整的 SPT-3G 调查将对 DES Y3 样本的平均星团质量实现约 5.7% 的约束。
