摘要
我们通过将专门定制的成分分离算法应用于来自 Planck 卫星巡天的 30 至 857 GHz 频率通道图，构建了热苏尼阿耶夫-泽尔多维奇（tSZ）效应的全天 y-图。这些重建的 y-图作为 Planck 2015 发布的一部分提供。y-图在噪声特性和残差前景污染方面被表征，主要包括大角尺度上的热尘埃辐射以及小角尺度上的宇宙红外背景（CIB）和河外点源。定义了特定掩膜以最小化前景残差和系统误差。利用这些掩膜我们计算了 y-图角功率谱和高阶统计量。由此我们得出结论：在多极范围 20-600 内 y-图由 tSZ 信号主导。我们将测量的 tSZ 功率谱和高阶统计量与各种物理动机模型比较，并讨论了我们的结果在星系团物理和宇宙学方面的含义。
