摘要
第 IV 期星系测量将提供前所未有的精度来检验宇宙模型及其 underlying 理论引力。在此背景下，Euclid 任务必须利用其光谱和光度探针来系统性地检验和纳入包括修正引力、替代暗能量情景、大质量轻子和原始非高斯性在内的非标准宇宙模型。我们生产并公开发布了来自广泛的非标准宇宙模拟的星系目录，这些模拟经过我们处理的管道处理，利用 Rockstar 进行星系识别，并使用修订版 SciPic 库实现星系-星系连接，采用星系分布函数框架。我们通过 2 点自相关函数的红移空间多极矩和 VDG，一种高性能的星系聚类模型，来探讨其星系聚类特征。在广泛的模型范围内，线性生长率乘以半径为 12 Mpc 的球内物质密度 fs12 对模型模板选择的选择性很强。与之前的工作相比，我们将这一结果扩展到大量具有显著不同引力或暗能量动力学的情景。我们发现大多数参数推断的散布在使用模拟的宇宙模型作为模板时已经呈现。使用“错误”模板也会引入额外的散布，尽管幅度较小。我们经常发现偏离误差棒的差异更大，这意味着协方差的高斯近似可能需要进一步研究。未来的宇宙调查必须扩大其范围，纳入超越 LCDM 和粗略动态暗能量模型的多样化非标准理论框架。
