利用天文数据研究暗物质和暗能量相互作用及其和修改引力模型的联系

探讨如何利用南极天文观测数据并结合国际上其他天文数据，利用高精度数值模拟技术、使用半解析方法与解析方法研究暗能量性质、暗能量和暗物质相互作用以及修改引力模型对宇宙大尺度结构的影响等重要基本问题。实现观测、理论和模拟三者的紧密结合，争取在理解宇宙加速膨胀这一前沿科学问题研究中取得有影响力的科学成果。

Explore the possibility on how to use the observational data from the south pole observation together with other available data to study the fundamental problems on the properties of dark energy, the interaction between dark energy and dark matter, the modified gravity and their effects on the cosmic large scale structure by employing high precision numerical simulations, the semi-analytic and analytic methods. Realize closely combined study among observation, simulation and theory. Try to get some breakthroughs in understanding the accelerated expansion of our universe.
