Recent theoretical work on large scale structure in cosmology has shown that the 2 and 3 point correlation functions contain important new corrections which allow for new tests of general relativity and the foundational equivalence principle on very large scales. The aim of this project is to develop the necessary tools to measure this new class of intrinsically relativistic observables in large-scale structure simulations.

最近在宇宙学大尺度结构方面的理论工作表明，2点和3点相关函数包含了重要的新修正，这使得在非常大的尺度上对广义相对论和基本等效原理进行新的检验成为可能。这个项目的目的是开发必要的工具来测量这类新的内在相对论性观测大规模结构模拟。
