摘要
毫米波天空的观测包含许多信号的有价值信息，包括黑体宇宙微波背景（CMB）、银河系辐射以及由热苏尼亚耶夫-泽尔多维奇（tSZ）效应引起的康普顿- 畸变。提取宇宙学和天体物理学问题的新见解通常需要结合多波长观测以在频谱上分离出某一成分。在这项工作中，我们呈现了一幅新的角分分辨率康普顿- 图，它示踪了视线积分的电子压强，以及跨越三分之一天空（约 13,000 平方度）的 CMB 强度和 E 模式偏振图。我们通过联合分析来自阿塔卡马宇宙学望远镜（ACT）数据发布 4 和 6 在约 93、148 和 225 GHz 频率的数据，以及来自 \textit{Planck} 卫星在 30 GHz 至 545 GHz 之间频率的数据来生成这些图。我们详细验证了在 needlet 框架下实现的内部线性组合流水线，它使我们能够高效抑制银河系污染并考虑 ACT 仪器噪声中的空间变化。这些图在噪声水平和分辨率上相比现有的 \textit{Planck} 成分分离图有显著进步，并将支持一系列科学目标，包括星系团和星系天体物理研究、宇宙速度场推断、原初非高斯性搜寻以及 CMB 引力透镜重建。
