Galactic HII regions in LAMOST Medium-Resolution Spectroscopic Survey of Nebulae
Yunning Zhao, Wei Zhang, Lin Ma +10
The paper uses LAMOST medium‑resolution spectra to confirm 255 Galactic H II regions in the outer Milky Way and measures their electron temperature, density, and oxygen abundance t…

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…

Spatially-resolved Galactic HII regions observed by LAMOST medium-Resolution Spectroscopic Survey of Nebulae (LAMOST MRS-N)
Wei Zhang, Yunning Zhao, Lin Ma +9
We present spatially-resolved spectroscopic observations of 10 isolated Galactic HII regions using data from the LAMOST Medium-Resolution Spectroscopic Survey of Nebulae (LAMOST MR…
