Transverse clues on the kiloparsec-scale structure of the circumgalactic medium as traced by C IV absorption [PDF]

The kiloparsec-scale kinematics and density structure of the circumgalactic medium (CGM) is still poorly constrained observationally, which poses a problem for understanding the role of the baryon cycle in galaxy evolution.

Studying the Circumgalactic Medium with MeerKAT

In order to understand how galaxies accrete gas from their surroundings and the impacts of feedback on quenching this accretion, it is necessary to study the circumgalactic medium (CGM).  While we have estimates of the total mass and metallicity of the CGM from UV absorption line studies, in order to understand the flow of gas onto and out of galaxy ...
