Abstract：

Since the birth of galaxies, most of their stars have formed in clusters, making the evolution of galaxies and star clusters inseparable. The globular clusters that formed in the early Universe, with their extremely high stellar densities, challenge existing theories of stellar and galactic evolution. During this talk, I will reveal the connections between the recent works of our research group, under the background of Milky Way evolution, including (1) the chemical evolution of the Sculptor dwarf galaxy, (2) the ripples of the galactic disk, (3) the star clusters of the Sagittarius dwarf galaxy, and (4) the escaped stars from globular clusters. Finally, I will also compare the studies of globular clusters in nearby galaxies and high-redshift galaxies to obtain a more complete evolutionary picture.

CV：

Baitian Tang is an associate Professor at the School of Physics and Astronomy, Sun Yat-sen University. He obtained his bachelor and master degrees from the Department of Astronomy, Nanjing University in 2007 and 2010. He obtained his Ph.D. from the Department of Physics and Astronomy from Washington State University in 2015. After finishing two-year postdoc. research in Chile, he joined Sun Yat-sen University in 2017. His personal research interests lie at using optical and near-infrared observational data to reveal the evolution of stellar systems (including star clusters and galaxies). To date, He has published more than 70 peer-reviewed papers.
