【DoA Colloquium】October 21st by Tao Wang (NJU)
Description
Title: New insights into galaxy formation and evolution in the early Universe by JWST
Speaker: Tao Wang (Nanjing University)
Abstract:
Since its successful launch in late 2021, the James Webb Space Telescope (JWST)'s powerful infrared detection capabilities have opened new windows for studying the early universe.
In this talk, I will review recent insights and challenges regarding the formation and evolution of galaxies and clusters in the early universe as revealed by JWST observations over the past few years.
These insights include searching for first-generation galaxies, investigating the overabundance of massive, bright galaxies, studying the early growth of massive black holes, and characterizing protoclusters in the early universe. Finally, I will discuss future opportunities and challenges for Chinese astronomers in this field.
Bio:
Tao Wang is a professor in the School of Astronomy and Space Science at Nanjing University. He received his Ph.D. from Nanjing University in 2012. From 2013 to 2016, he was a postdoctoral fellow at CEA-Saclay in France. He then moved to the University of Tokyo in Japan, where he completed a second postdoctoral fellowship from 2017 to 2020. In 2021, he joined Nanjing University as a faculty member.
His research focuses on the formation and evolution of massive galaxies and galaxy clusters over cosmic time, using multi-wavelength observations from some of the world's most powerful optical, submillimeter, and radio telescopes. His main scientific findings include providing key observational evidence of the fundamental role of supermassive black holes in regulating the cool gas content of massive galaxies; revealing the prevalence of optically invisible massive galaxies in the early universe; and discovering the most distant known X-ray cluster.
Time: 14:00-15:00, 21/October, Tuesday
