The project is to use large cosmological hydrodynamical simulations to study the effects of time-varying dark energy and modified gravity on large-scale structure. Significant modification of the simulation code is required to include these effects. Particular attention will be focused on assessing the effects on directly observable quantities, such as weak gravitational lensing (cosmic shear), CMB lensing, galaxy clustering, and the thermal Sunyaev Zel'dovich effect.

该项目是利用大型宇宙流体力学模拟来研究时变暗能量和修正重力对大尺度结构的影响。需要对模拟代码进行重大修改以包含这些效果。特别关注将集中在评估对直接可观测量的影响，如弱引力透镜（宇宙剪切）、CMB透镜、星系群集和热Sunyaev Zel'dovich效应。
