摘要
高精度微波背景观测,加之大尺度结构,超新星等观测的快速发展,引领宇宙学进入精确宇宙学时代.我们对于宇宙的理解不再停留在定性描述阶段,而是进入了高精度定量测量阶段.本文将对重要宇宙学观测给出介绍,并对研究现状,及未来挑战等给出讨论.
High precision cosmological observations,including cosmic microwave background anisotropy,large-scale structures of the universe,type Ia supernovae,etc.,have opened the era of precision cosmology. Nowadays,our understanding about the universe is far from qualitative sketches,and we can measure important cosmological parameters at the precision of a few percents. In this paper,after describing various cosmological observations and their underlying physics. I will discuss the current status of precision cosmology and its future potentials and challenges.
