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…

LAMOST Medium-resolution Spectroscopic Survey of the Rosette Nebula

Li-Yue Zhang, Chao-Jian Wu, Xuan Fang +4

We report multi-fiber, medium-resolution spectroscopy of the Rosette Nebula with full spatial coverages, and present a table of the nebular parameters based on the spatially-resolv…

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…

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…
