摘要
本文是HOWLS（更高阶弱引力统计）系列论文第二篇，探讨了在欧亚（Euclid）项目中应用非高斯统计进行宇宙学推断。相较于第一篇，我们发展了基于真实光度红移系数的完整切片分析，允许我们为欧亚类数据释放第一次（DR1）设置推算出在（, ）平面上的Fisher预测。我们发现，五种满足Fisher形式中高斯似然假设的更高阶统计量（一点概率分布函数、1范数、峰值计数、Minkowski函数以及Betti数）相较于剪切双点相关函数，在预测上均提升了倍的性能；仅在与双点估计器组合使用时才略有提升，这表明每种更高阶统计量都能从物质密度场中检索到非高斯与高斯信息。不同估计器相似性能的解释在于：对多尺度与切片信息进行了均匀化处理，以降低计算成本。这些结果适用于欧亚流水线的三种质量映射技术：孔径质量、Kaiser- Squires以及Kaiser- Squires加，亦不受现实星掩模应用的影响。最后，我们探索了采用Bernardeau- Nishimichi- Taruya（BNT）空化方案处理更高阶统计量，发现其在对更高阶统计量应用物理尺度切割方面具有前景。
