我们对从暗能量调查(DES)第一年数据集中选择的redMaPPer星团的计数和弱透镜信号进行了联合分析。我们的分析使用了与DES组合探针分析中使用的相同的剪切和源光度红移估计。我们的分析结果是，在低物质密度参数的驱动下，与DES Y1 3x2pt结果和Planck CMB分析的后方强度的值令人惊讶地低。这些结果包括解盲后的变化对分析的影响，与解盲时获得的结果相比，这并没有提高与其他数据集的一致性水平。事实上，多种宇宙学探测器(超新星、重子声振荡、宇宙切变、星系团和CMB各向异性)和其他星系团分析都倾向于更高的物质密度，这表明数据中存在系统误差或相关物理模型的不完整。与X射线和微波数据的交叉验证，以及对Sunyaev-Zeldovich选定星系团的可观测质量关系的独立约束，表明差异存在于我们对弱透镜信号的建模，而不是星系团丰度。使用更高的丰富度阈值()重复我们的分析可以显著减少与其他探测器的紧张关系，并指向我们的模型没有捕捉到的一个或多个依赖丰富度的效果。
We perform a joint analysis of the counts and weak lensing signal of redMaPPer clusters selected from the Dark Energy Survey (DES) Year 1 dataset. Our analysis uses the same shear and source photometric redshifts estimates as were used in the DES combined probes analysis. Our analysis results in surprisingly low values for, driven by a low matter density parameter,, withposteriors intension with the DES Y1 3x2pt results, and inwith thePlanckCMB analysis. These results include the impact of post-unblinding changes to the analysis, which did not improve the level of consistency with other data sets compared to the results obtained at the unblinding. The fact that multiple cosmological probes (supernovae, baryon acoustic oscillations, cosmic shear, galaxy clustering and CMB anisotropies), and other galaxy cluster analyses all favor significantly higher matter densities suggests the presence of systematic errors in the data or an incomplete modeling of the relevant physics. Cross checks with x-ray and microwave data, as well as independent constraints on the observable-mass relation from Sunyaev-Zeldovich selected clusters, suggest that the discrepancy resides in our modeling of the weak lensing signal rather than the cluster abundance. Repeating our analysis using a higher richness threshold () significantly reduces the tension with other probes, and points to one or more richness-dependent effects not captured by our model.
