报告人简介：Guangxing Li is a post-doctoral researcher at Universitats-Sternwarte Munchen, Germany. His research focuses on the formation of stars and the dynamics of the interstellar medium. Guangxing obtained his B.S. degree in Electronics at Peking University in 2007, M.S. degree in Astrophysics at the USTC in 2010, and PhD degree in Astrophysics at the Max-Planck Institute for Radio Astronomy in 2014.
摘要：Different from the Milky Way, disks of gas-rich galaxies are clumpy. It remains a mystery why they are clumpy and how star formation occurs in these clumps. Molecular clouds constitute a significant fraction of the total mass of galactic disks, and they play important roles in disk dynamics. I will present some recent observational results, and discuss how dynamics of molecular clouds on pc scale influences the dynamics of galactic disk at kpc scale and lead to the formation of giant clumps.
