摘要
验证宇宙微波背景（CMB）偶极子的完全运动学性质在宇宙学中具有根本重要性。在具有来自暴胀膨胀的弗里德曼-勒梅特-罗伯逊-沃尔克（FLRW）度规的标准宇宙学模型中，CMB偶极子应完全是运动学的。因此，任何非运动学的CMB偶极子成分都将反映暴胀前的时空结构，探测FLRW的适用范围。来自物质-辐射退耦后星系的宇宙背景，应具有与CMB运动学偶极子在速度上完全相同的运动学偶极子成分。比较两者可以导致分离出CMB非运动学偶极子。最近有人提出，这种测量可以利用目前运行的欧几里得望远镜以及后来的罗曼望远镜测量的近红外宇宙红外背景（CIB）来完成。所提出的方法从欧几里得的广域巡天中重建已解析的CIB，即集成星系光（IGL），并探测其偶极子，其运动学成分通过康普顿-盖廷效应相对于CMB的偶极子被放大。这种放大与形成IGL的广泛星系样本相结合，将以压倒性的信噪比确定CIB偶极子，将其方向隔离到亚度精度。我们为欧几里得在跨越0.6至2微米的4个波段中的广域巡天开发了该方法的细节。我们隔离了系统误差和其他不确定性，并提出了最小化它们的方法，在将样本限制在星系聚类引起的IGL/CIB偶极子可忽略不计的星等范围内之后。这些包括所需的恒星-星系分离，使用此处新开发的方法计算消光校正偶极子以实现完全分离，考虑地球轨道运动和其他系统效应。（节略）
