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…

Misaligned external gas acquisition boosts central black hole activities
Yuren Zhou, Yanmei Chen, Yong Shi +6
One important question in active galactic nucleus (AGN) is how gas is brought down to the galaxy center. Both internal secular evolution (torque induced by non-axisymmetric galacti…

Misaligned gas acquisition as a formation pathway of S0 galaxies
Yuren Zhou, Yanmei Chen, Yong Shi +3
We analyze a sample of 753 S0 galaxies from the MPL-10 of MaNGA survey and investigate the gas-star kinematic misalignment and merger remnant fraction in galaxies with different mo…
