The Vertical Structure and Asymmetry of Mg ii-enriched Gas in the Milky Way Disk

Xiaochuan Jiang, Taotao Fang, Shulan Yan

The physical properties of Milky Way Mgii-bearing gas remain poorly constrained due to the saturation of the near-UV doublet. We utilize the weaker Mgii $\hat{I}»\hat{I}»$1239, 1240 doublet fr…
