摘要
我们提出 Planck 似然，即对 CMB 温度涨落两点相关函数的完整统计描述。我们利用该似然推导了跨越三个 量级的 Planck CMB 功率谱，覆盖 。在 时，主要误差来源是宇宙方差。在更高 处，小尺度前景建模和仪器噪声的不确定性主导了误差预算。对于 ，我们的似然通过物理驱动的贝叶斯成分分离技术利用了从 30 到 353 GHz 的所有 Planck 频率通道。在 时，我们采用了基于 100、143 和 217 GHz 通道角交叉谱的相关高斯似然近似。我们通过一系列一致性测试验证了我们的似然，并评估了残余前景和仪器不确定性对宇宙学参数的影响。我们发现高 交叉谱之间内部一致性良好，在 处残差为几 。我们将结果与去除前景的 CMB 图以及从 70 GHz Planck 图导出的交叉谱进行了比较，发现在谱残差和宇宙学参数方面广泛一致。最佳拟合的 LCDM 宇宙学与初步的 Planck 偏振谱高度一致。标准 LCDM 宇宙学被 Planck 在 范围内很好地约束。例如，我们报告了 的 偏离。考虑标准模型之外的各种扩展，我们没有发现显著偏离 LCDM 框架的迹象。最后，我们报告了最佳拟合 LCDM 模型与低 谱之间的张力，表现为在 处有 5-10% 的功率亏损，显著性为 。我们不进一步阐述其宇宙学含义，但指出这是在该数据集其他方面显著一致的情况下最令人困惑的发现。（节选）
