Title: Angular momenta of galaxies to probe primordial universe

Speaker: Hao-Ran Yu, Department of Astronomy, Xiamen University

Host: Mouyuan Sun

Time: 14:30-16:30, Thursday, Sept. 17

Location: Physics Building 552

Abstract: 

I will discuss the origin, numerical simulation and observation of the angular momenta of galaxies, and how they can constrain the initial properties of the Universe.
