What factors shape the radio luminosity of star-forming galaxies? A new calibration from LoTSS-DR2
Shravya Shenoy, Daniel J. B. Smith, Sarah K. Biddle +8
Radio observations offer a dust-unobscured view of galaxy star formation via the radio continuum-star formation rate (RC--SFR) relation. Emerging evidence of a stellar mass depende…

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…
