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…

The diverse physical origins of stars in the dynamically hot bulge: CALIFA vs. IllustrisTNG
Le Zhang, Ling Zhu, Annalisa Pillepich +3
We compare the internal stellar structures of central galaxies in the TNG50 and TNG100 simulations and field galaxies in the CALIFA survey. The luminosity fractions of the dynamica…
