摘要
随着宇宙学测量的统计精度不断提高，对这些测量的理论描述的准确性也需要相应提高，以便推断支配宇宙的基本宇宙学。为此，我们在Euclid合作组内创建了Euclid可观测量宇宙学似然函数（CLOE），这是一个新型的宇宙学参数推断流水线，用于将测量结果和协方差转化为宇宙学参数约束。在本系列六篇论文的第一篇中，我们描述了该代码针对Euclid主要探针的理论方案。这些探针由宇宙剪切、星系-星系透镜和星系聚类的测光3x2pt可观测量，以及光谱星系聚类组成。我们同时在傅里叶空间和构型空间中为标准和扩展的汇总统计量提供了该描述，涵盖影响它们的一系列系统不确定性。这包括固有星系对齐、重子反馈、测光和光谱红移不确定性、剪切标定不确定性、样本污染、测光和光谱星系偏差以及放大偏差等系统不确定性。理论描述还能够兼容高斯和非高斯似然函数，以及具有非零曲率、大质量中微子、演化暗能量和简单形式修正引力的扩展宇宙学。这些支撑CLOE的理论描述将成为下一代宇宙学巡天（如Euclid）揭示宇宙真实本质的关键组成部分。
