摘要
我们给出了来自 Planck 全任务数据集的星系团计数及相应的宇宙学约束。我们的星表包含 439 个通过其苏尼阿耶夫-泽尔多维奇（SZ）信号探测到的星系团，信噪比低至 6，比 2013 年 Planck 星系团宇宙学样本大两倍以上。计数与 2013 年的一致，并在相同建模假设下给出兼容的约束。利用更大的星表，我们将分析扩展到红移和信噪比的二维分布。我们使用来自最近两项关于 Planck 星系团对背景星系引力透镜研究的质量估计，为流体静力偏差参数 提供先验。此外，我们使用 Planck 星系团对宇宙微波背景（CMB）温度涨落的透镜效应作为对该参数的独立约束。这些不同的校准对当前物质涨落振幅给出了约束，与来自 Planck 对 CMB 原初涨落分析的约束存在不同程度张力；对于最低的 估计值，张力温和，仅略高于一个标准偏差，而对于最大的估计值张力仍然显著（）。我们还通过结合星系团和 CMB 约束检验了对基础平坦 CDM 模型扩展的约束。该组合似乎倾向于非最小中微子质量，但这一可能性对缓解整体张力作用甚微，因为它同时降低了隐含的哈勃参数值，从而加剧了与当前大多数天体物理估计的差异。将星系团质量校准精度从当前的 10% 水平提高到 1% 将显著加强这些组合分析，并为基准 CDM 模型提供严格检验。
