报告题目:Make it, Mix it and Shake it — a recipe for cold gas in circumgalactic medium

  报告人:季索清 博士(University of California, Santa Barbara)

  摘要:Multiphase gas structure is ubiquitous in our universe. Recent results from COS suggest that large quantities of cold gas with temperature of a few 10^4 K are found in circumgalactic medium (CGM), which extends up to galactic virial radius (~ 100 kpc). However, the origin and fate of such cold gas still remain unclear. In this talk, I will mainly explore magnetized thermal instability as a promising mechanism for cold gas formation. In addition, I will briefly discuss warm gas generation from MHD turbulent mixing layers, and preferential concentration of cold droplets in hot winds in CGM.
