Cooler Phases of the Circumgalactic Medium Are More Centrally Concentrated: Constraints from Multiphase Absorption Lines

Weiwen Kong, Zeyu Chen, Enci Wang +7

We present a systematic study of the multiphase circumgalactic medium (CGM) around galaxies and quasars, traced by Ca II $\hat{I}»\lambda 3934,3969$, Mg II $\hat{I}»\lambda 2796,2803$, and C IV…
