摘要
Euclid 任务旨在测量超过十亿星系的位置、形状与红移，以提供对暗物质与暗能源本质的前所未有约束。实现这一目标需要不断重新评估任务的科学性能，尤其是其在约束 cosmological 参数方面的能力，随着我们对如何建模大尺度结构观测数据的理解不断提升。在本研究中，我们展示了首次使用 CLOE (Cosmology Likelihood for Observables in Euclid) 的科学预测，该系统为支持这一目标而开发。运用应用于合成 Euclid 类数据的先进贝叶斯推断技术，我们对包括多种 cosmological 模型和 Euclid 主导探针：星系形变、角光度星系聚类、星系-星系引力透镜以及光谱星系聚类，在这些探针下的 cosmological 与 nuisance 参数后验分布进行采样。我们验证了 CLOE 能够产生可靠 cosmological 预测，展示了 Euclid 可能实现对暗能源参数 与 的 Figure of Merit 超过 400 的潜力。进一步地，我们说明了给定不同先验与尺度切割时，感兴趣参数后验概率分布的行为。最后，我们强调了面临计算挑战的重要性，提出进一步探索创新数据科学技术，以高效地导航 Euclid 高维参数空间，为即将到来的 cosmological 数据发布做好准备。
