报告题目：Circum-galactic Medium Around Local Spiral Galaxies --- A New Window to Understand Galaxy Evolution

　　报 告 人：李江涛（CEA-Saclay, France and Univ. Michigan, USA）

　　摘    要：The multi-phase circum-galactic medium (CGM) plays a key role in galaxy evolution as a reservoir where galaxies acquire baryons to continue their SF and deposit chemically enriched materials and mechanical feedback. I will introduce our recent work and ongoing projects studying the X-ray emitting hot galactic coronae around local disk galaxies, as well as some other multi-wavelength projects. I will also discuss how these observations could improve our understanding of the total baryon budget, metal enrichment, and dynamics of the CGM.
