摘要/Abstract:

Galaxy groups and clusters are the least massive systems where the bulk of baryons are accounted for and also the most massive systems that are gravitationally bound. They contain a wealth of galaxies sampling the broad spectra of galaxy properties, including the most massive galaxies (and probably the most massive supermassive black holes) and galaxies with the highest velocities in the universe. Galaxy groups and clusters are then ideal systems to study cosmic structure formation and the related baryon physics in multi-phase media. In this talk, I will summarize our works on two kinds of multi-phase objects with synergy in galaxy groups and clusters, X-ray cool cores around the central galaxies and stripped tails behind satellite galaxies. New results from multi-wavelength data, including those from XRISM, MUSE, JWST and ALMA, will be presented, with the implications and future prospects discussed.

个人简介/Biography:

Ming Sun is a professor of Physics and Astronomy at the University of Alabama in Huntsville. He obtained his PhD degree on Astronomy from Harvard University in 2005. After postdocs at the Michigan State University and University of Virginia, he started as an assistant professor at the UAH in 2014 and was promoted to professor in 2022. His research group currently has three postdocs and five students, working on AGN feedback, galaxy evolution and baryons in galaxy groups and clusters, with multi-wavelength data.
