摘要
Euclid 任务将以前所未有的精度测量宇宙学参数。为了区分不同的宇宙学模型，必须从既在标准 -冷暗物质(CDM)范式下运行的宇宙学模拟，也在许多超越 CDM 的非标准模型下运行的宇宙学模拟中，生成真实的模拟观测量。我们展示了使用非标准模型（包括动力学暗能量、k-essence、相互作用暗能量、修改引力、大质量中微子和原初非高斯性）的一套宇宙学 N 体模拟的科学结果。我们研究了这些模型如何影响大尺度结构的形成和演化，并提供了可用于利用 Euclid 数据测试和约束这些模型的合成观测量。我们开发了一个基于 Rockstar 暗物质晕查找器和 nbodykit 大尺度结构工具包的自定义流水线，以一致的方式分析非标准模拟的粒子输出，并生成模拟观测量，如暗物质晕和空洞目录、质量密度场以及功率谱。我们将这些观测量与标准 CDM 模型的观测量进行比较，并量化了偏差。我们发现，非标准宇宙学模型可以在我们生成的合成观测量上留下显著的印记。我们的结果表明，非标准宇宙学 N 体模拟为暗能量和暗物质的物理学提供了有价值的见解，这对于最大化 Euclid 的科学回报至关重要。
