X-ray scaling relations of early-type galaxies in IllustrisTNG and a new way of identifying backsplash objects
Yunchong Wang, Mark Vogelsberger, Dong-Woo Kim +9
We investigate how feedback and environment shapes the X-ray scaling relations of early-type galaxies (ETGs), especially at the low-mass end. We select central-ETGs from the Illust…
Baryonic Effects on Lagrangian Clustering and Angular Momentum Reconstruction
Ming-Jie Sheng, Hao-Ran Yu, Sijia Li +7
Recent studies illustrate the correlation between the angular momenta of cosmic structures and their Lagrangian properties. However, only baryons are observable and it is unclear w…
Early-type galaxy density profiles from IllustrisTNG: III. Effects on outer kinematic structure
Yunchong Wang, Shude Mao, Mark Vogelsberger +10
Early-type galaxies (ETGs) possess total density profiles close to isothermal, which can lead to non-Gaussian line-of-sight velocity dispersion (LOSVD) under anisotropic stellar or…
Quenched, bulge-dominated, but dynamically cold galaxies in IllustrisTNG and their real-world counterparts
Shengdong Lu, Dandan Xu, Sen Wang +5
Galaxy morphologies, kinematics, and stellar populations are thought to be linked to each other. However, both simulations and observations have pointed out mismatches therein. In…
UniverseMachine: Predicting Galaxy Star Formation over Seven Decades of Halo Mass with Zoom-in Simulations
Yunchong Wang, Ethan O. Nadler, Yao-Yuan Mao +3
We apply the empirical galaxy--halo connection model UniverseMachine to dark matter-only zoom-in simulations of isolated Milky Way (MW)--mass halos along with their parent cosmolog…
Hot and counter-rotating star-forming disk galaxies in IllustrisTNG and their real-world counterparts
Shengdong Lu, Dandan Xu, Yunchong Wang +7
A key feature of a large population of low-mass, late-type disk galaxies are star-forming disks with exponential light distributions. They are typically also associated with thin a…
Star Formation in Massive Galaxies at Redshift
Kun Xu, Chengze Liu, Yipeng Jing +2
It is believed that massive galaxies have quenched their star formation because of active galactic nucleus feedback. However, recent studies have shown that some massive galaxies a…
Early-type galaxy density profiles from IllustrisTNG: II. Evolutionary trend of the total density profile
Yunchong Wang, Mark Vogelsberger, Dandan Xu +8
We study the evolutionary trend of the total density profile of early-type galaxies (ETGs) in IllustrisTNG. To this end, we trace ETGs from to and measure the power-law…
Redshift Evolution of the Fundamental Plane Relation in the IllustrisTNG Simulation
Shengdong Lu, Dandan Xu, Yunchong Wang +7
We investigate the fundamental plane (FP) evolution of early-type galaxies in the IllustrisTNG-100 simulation (TNG100) from redshift to . We find that a tight plane rela…
SDSS--IV MaNGA : The Inner Density Slopes of nearby galaxies
Ran Li, Hongyu Li, Shi Shao +12
We derive the mass weighted total density slopes within the effective (half-light) radius, , for more than 2000 nearby galaxies from the SDSS-IV MaNGA survey using Jeans-anisot…
Early-type galaxy density profiles from IllustrisTNG: I. Galaxy correlations and the impact of baryons
Yunchong Wang, Mark Vogelsberger, Dandan Xu +10
We explore the isothermal total density profiles of early-type galaxies (ETGs) in the IllustrisTNG simulation. For the selected 559 ETGs at with stellar mass $10^{10.7}\mat…
