Decomposing the Kinematics of SNR G180.0-01.7 with Medium-Resolution Spectra
Juan-Juan Ren, Wei Zhang, Chao-Jian Wu +3
The exceptionally large angular diameter and intrinsic optical faintness of the Galactic supernova remnant (SNR) G180.0-01.7 (S147) have historically hindered a comprehensive spect…

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 th…
