摘要
Planck 卫星的多频率能力提供了关于恒星形成的积分历史（通过宇宙红外背景，或 CIB）以及暗物质分布（通过其对宇宙微波背景，或 CMB 的透镜效应）的信息。这两种独特探针的结合使我们能够直接测量高红移（1 < z <3）宇宙中暗物质与发光物质之间的联系。我们使用优化用于检测这两种示踪剂之间相关性的三点统计量。在全面讨论了可能的污染源并进行了一系列一致性检验后，使用 100、143 和 217 GHz 的透镜重建以及 100-857 GHz 的 CIB 测量结果，我们报告了 CIB 与 CMB 透镜之间相关性的首次探测。这两种信号的红移分布高度匹配，使得在 545 GHz 处的探测显著性达到峰值 42 \sigma，并且在这两种示踪剂之间的相关性高达 80%。我们的全套多频率测量结果（包括 CIB 自功率谱和 CIB-透镜交叉功率谱）与一个简单的基于晕的模型一致，其中宿主 CIB 源的晕的特征质量尺度为 log_{10}(M/M_sun) = 10.5 \pm 0.6。利用我们信号的频率依赖性，我们分离了 CIB 的高红移贡献，并约束了 z>1 处的恒星形成率（SFR）密度。我们在 z=1 到 7 之间的三个红移箱中以约 2 \sigma 的显著性直接测量了 SFR 密度，从而为研究早期恒星形成打开了一扇新窗口。
