Unifying the dynamical classification of early-type galaxies: kinematic deficits in IllustrisTNG versus observations
Wenyu Zhong, Min Du, Shengdong Lu +2
We conduct a comparative analysis of galaxy kinematics using IllustrisTNG simulations and integral-field spectroscopy (IFS) observations. We identify 2,342 early-type galaxies (ETG…

Implications for galaxy property estimation revealed by CO luminosity-FWHM relations in local star-forming galaxies
Yi-Han Wu, Jun-Feng Wang, Xiao-Hu Li +6
This study explores a relationship between the CO luminosity-full width at half-maximum linewidth linear relation (i.e. the CO LFR) and mean galaxy property of the local star-formi…

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…
