The size-velocity dispersion relationship of Galactic HII regions
Lin Ma, Yunning Zhao, Wei Zhang +11
The size-velocity dispersion () relation, while well established for giant HII regions, remains uncertain for their smaller counterparts (physical radii R < 20 pc). Thanks to t…

Diffuse Ionized Gas in the Anti-center of the Milky Way
Shiming Wen, Wei Zhang, Lin Ma +10
Using data from the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae, we create a sample of 17,821 diffuse ionized gas (DIG) spectra in the anti-center region of the Milky…
