Probing the Large Scale Structure of the Universe

我提出了一个研究计划，通过对无线电和微波天空的观测，以探测和表征宇宙的大尺度结构（LSS）为中心。这项研究将探索120亿年宇宙历史中结构的发展，以回答有关我们生活的宇宙的基本问题。结构（在这种情况下，星系和星系团）是如何形成的？爱因斯坦的广义相对论能解释宇宙尺度上的引力吗？“暗能量”的本质是什么？“暗能量”是一种被提出来解释宇宙加速的负压流体。

I propose a program of study centered on detecting and characterizing the Large Scale Structure (LSS) of the Universe through observations of the radio and microwave sky. This research will probe the development of structure over 12 billion years of cosmic history, in order to answer fundamental questions about the Universe we live in. How did structure (in this context, galaxies and clusters of galaxies) form? Does Einstein's General Relatively explain gravity on cosmic scales? What is the nature of "Dark Energy," the negative pressure fluid proposed to explain cosmic acceleration?
