摘要
即将到来的 数据与宇宙微波背景（CMB）测量的结合与交叉相关备受期待，因为它将提供从复合时期到整个过去光锥上结构形成的最大红移跨度。在本工作中，我们给出 与 CMB 数据在标准宇宙学模型及其若干扩展的宇宙学参数上的联合分析预测。本工作扩展并补充了近期基于 专用探针（即星系成团、弱引力透镜及其交叉相关）发布的预测。在对当前与未来 CMB 实验的规格作若干假设下，预测约束由标准 Fisher 形式体系以及基于实际 CMB 数据的后验拟合方法得到。与仅 的分析相比，加入 CMB 数据对所有标准 冷暗物质模型宇宙学参数的约束产生实质性影响，改进可达十倍。对于包含红移依赖暗能量状态方程、非零曲率以及引力唯象修正的扩展模型参数，改进可达二到三倍量级，某些情况下高于十倍。结果凸显了 探针与 CMB 数据结合及交叉相关对宇宙学约束的关键重要性。
