The evolutionary pathways of disk galaxies with different sizes
Hong-Chuan Ma, Min Du, Luis C. Ho +2
From the IllustrisTNG-50 simulation, a sample of 836 central disk galaxies with tiny stellar halos is chosen to study the inherent evolution of galaxies driven by nature. These gal…

The Physical Origin of the Mass-Size Relation and Its Scatter of Disk Galaxies
Min Du, Hong-Chuan Ma, Wen-Yu Zhong +3
Utilizing a kinematic decomposition of simulated galaxies, we focus on galaxies with tiny kinematically inferred stellar halos, indicative of weak external influences. We investiga…

Spin speed correlations and the evolution of galaxy-halo systems
Ming-Jie Sheng, Lin Zhu, Hao-Ran Yu +4
Galaxy angular momenta (spins) contain valuable cosmological information, complementing their positions and velocities. The baryonic spin direction of galaxies has been probed as a…
