报告题目：Probing the cosmic expansion with redshift surveys: prospects and theoretical challenges

　　报 告 人：景益鹏教授 （上海交通大学）

　　摘    要：Expansion of the Universe is found to be accelerating. Mysterious dark energy is one possible solution to explain the acceleration, and modifying the gravity theory is another. In order to find out what is driving the cosmic accelerating expansion, astronomers are carrying out huge observational projects. One powerful probe is the redshift distribution of galaxies on large scales. I will introduce the basic information of this observation and summarize the current status. Then I will introduce the future observations, especially the MS-DESI project, and outline theoretical challenges.
