星系的角动量和原初宇宙的探针 / Angular momenta of galaxies to probe primordial universe

  • 2020年秋季

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.

Bio: 

In 2005-2014, Dr. Hao-Ran Yu got Bachelor and Ph.D. in Astrophysics (Beijing Normal University). Then he was a joint postdoc fellow in Kavli Institute for Astronomy and Astrophysics (Peking University), Canadian Institute for Theoretical Astrophysics (University of Toronto) and Tsung-Dao Lee Institute (Shanghai Jiao Tong University). From 2019, he joined Department of Astronomy, Xiamen University as an Associate Professor. His research and teaching interests include cosmology, large scale structure of the Universe, high performance computing etc.
