The Velocity Map Asymmetry of Ionized Gas in MaNGA II. Correlation between Velocity Map Morphology, Star Formation, and Metallicity in Regular Disk Galaxies
Shuai Feng, Shiyin Shen, Yanmei Chen +5
The morphology of ionized gas velocity maps provides a direct probe of the internal gas kinematics of galaxies. Using integral field spectroscopy from SDSS-IV MaNGA, we analyze a s…

The origin of double-peaked narrow emission-line galaxies in MaNGA Survey
Zhiyun Zhang, Yanmei Chen, Shiyin Shen +5
We select 36 double-peaked narrow emission-line galaxies (DPGs) from 10,010 unique galaxies in MaNGA survey. These DPGs show double-peaked Balmer lines and forbidden lines in the s…
