我们对暗能量勘测第一年 (DES-Y1) 数据中的红色序列匹配滤波器概率渗流算法 (redMaPPer) 选择的星团目录进行了交叉验证，方法是将其与来自南极望远镜 SPT-SZ 勘测的 Sunyaev-Zel'dovich 效应 (SZE) 选择的星团目录相匹配。在 1005 个 redMapPer 选择的具有测量联合足迹丰富度的簇中，有 207 个被 SPT-SZ 确认。利用来自 SZE 信号的质量信息，我们使用贝叶斯聚类种群模型校准丰富度-质量关系。我们发现质量趋势 λ ∝MB 与线性关系 (B∼ 1) 一致，没有显着的红移演化，丰富度的内在散射为 σλ= 0.22 ± 0.06。通过考虑两个误差模型，我们探讨了投影效应对丰富度-质量建模的影响，确认在当前的系统不确定性水平下无法检测到这种效应。在低丰富度下，SPT-SZ 确认的 redMaPPer 簇比预期少。我们将已确认系统中这种与丰富度相关的缺陷解释为由于低质量物体在低丰富度下的存在增加，而我们的丰富度-质量散射模型没有正确解释这些物体，我们将其称为污染物。从富裕程度来看，这一人口占总人口的比例（97.5%）。以此推断出测量的丰富度产量（97.5%）。有了这些污染分数，不同可信宇宙学中预测的 redMapPer 计数与测量的丰度是一致的。这种群体的存在也是对使用纯光学选择的簇进行质量校准获得的不同质量趋势（B∼0.75）的合理解释。堆叠弱透镜 (WL) 测量的平均质量表明，这些低质量污染物是质量为 ∼3–5 × 1013M⊙ 的星系团，超出了当前 SZE 和 X 射线巡天的灵敏度，但却是 SPT-3G andeROSITA 的自然目标。
We perform a cross validation of the cluster catalogue selected by the red-sequence Matched-filter Probabilistic Percolation algorithm (redMaPPer) in Dark Energy Survey year 1 (DES-Y1) data by matching it with the Sunyaev–Zel’dovich effect (SZE) selected cluster catalogue from the South Pole Telescope SPT-SZ survey. Of the 1005 redMaPPer selected clusters with measured richnessin the joint footprint, 207 are confirmed by SPT-SZ. Using the mass information from the SZE signal, we calibrate the richness–mass relation using a Bayesian cluster population model. We find a mass trend λ ∝MBconsistent with a linear relation (B∼ 1), no significant redshift evolution and an intrinsic scatter in richness of σλ= 0.22 ± 0.06. By considering two error models, we explore the impact of projection effects on the richness–mass modelling, confirming that such effects are not detectable at the current level of systematic uncertainties. At low richness SPT-SZ confirms fewer redMaPPer clusters than expected. We interpret this richness dependent deficit in confirmed systems as due to the increased presence at low richness of low-mass objects not correctly accounted for by our richness-mass scatter model, which we call contaminants. At a richness, this population makes up(97.5 percentile) of the total population. Extrapolating this to a measured richnessyields(97.5 percentile). With these contamination fractions, the predicted redMaPPer number counts in different plausible cosmologies are compatible with the measured abundance. The presence of such a population is also a plausible explanation for the different mass trends (B∼ 0.75) obtained from mass calibration using purely optically selected clusters. The mean mass from stacked weak lensing (WL) measurements suggests that these low-mass contaminants are galaxy groups with masses ∼3–5 × 1013M⊙which are beyond the sensitivity of current SZE and X-ray surveys but a natural target for SPT-3G andeROSITA.
