Mapping Warm and Hot CGMs in Emission

Speaker: Li Ji (PMO)

Venue: Room 2111, SWIFAR Building

Abstract:

Mapping the  circumgalactic medium (CGM) in emission is one of the important scientific goals for astronomers to either use the modern ground-based telescopes or the future space missions.  CGMs are multi-phases, key to understand  the galaxy evolution.  In this talk, I will briefly introduce a few projects in our group for the efforts to mapping warm and hot CGMs in emission.  In addition, I will introduce our proposed space missions for  mapping CGMs in Lyman UV emission. One is the small UV explorer CAFE (Census of WHIM, Accretion and Feedback Explorer) and the independent external payload LyRIC (Lyman UV Radiation from ISM and CGM) operating on the Chinese Space Station.
