报告题目：Cosmology and Astrophysics with the cosmic web 

　　报告人：Dr Cai Yanchuan ，The University of Edinburgh 

　　摘要：On large scales, the matter distribution of the Universe follows a web-like pattern, consisting of cluster, filament, sheet and void. The cosmic-web contains invaluable information about cosmology and provides the environment for galaxy formation. It is the junction where cosmology and astrophysics meet. I will summarize recent research activities in this area, using the following examples: (1) dynamical analysis and gravitational redshift around galaxy clusters; (2) detection of gas filament and missing baryons; (3) cosmology with cosmic voids.
