报告题目：充满重元素的高红移星系周气体

报告人：蔡峥 副教授（清华大学天文系副主任）

报告摘要：In this talk, I will present our survey of circumgalactic medium from z=2--6 through both emission and absorption. Using JWST, Keck, combined with the Subaru/HSC, ALMA and VLA, we studied the detailed kinematics of the circumgalactic medium (CGM). Combined with simulations, our observations suggest that CGM could be heavily metal enriched, and the recycled inflow play a vital role in star foramtion at high-redshift. This could be a reason of the rapid formation of the structure found by recent JWST observations. I will also talk about the future of MUltiplexed Survey Telescope (MUST).
