摘要
我们利用普朗克卫星的观测检验宇宙微波背景(CMB)各向异性的统计各向同性和高斯性。我们的结果主要基于完整的普朗克任务温度数据，但也包括一些偏振测量。特别地，我们考虑由多种成分分离方法从多频普朗克数据导出的CMB各向异性图。对于温度各向异性，我们发现基于这些天空图的结果在天空的很大一部分和广泛角尺度上高度一致，确定潜在的前景残差不影响我们的研究。偏度、峰度、多元正态性、N点函数和闵可夫斯基泛函的检验表明与高斯性一致，而大角尺度上的功率亏损以几种方式显现，例如低地图方差。峰值统计分析与高斯随机场的期望一致。“冷斑”被多种方法探测到，包括地图峰度、峰值统计和平均温度轮廓。我们彻底探查大尺度偶极功率不对称性，用几种独立检验探测到它，并处理后验修正问题。方向性检验暗示从大尺度到小尺度存在角聚类，但显著性依赖于方法的细节。我们执行首次偏振数据检验，发现堆叠峰值的形态与统计各向同性模拟的期望一致。在重叠处，这些结果与基于标称任务数据的普朗克2013分析一致，并提供了迄今为止我们对CMB涨落统计最透彻的视图。
