Dynamically cold discs in high-redshift galaxies: comparison between ALMA observations and TNG50
Yi He, Qi Guo, Filippo Fraternali +2
Observations of highly rotationally supported gas discs in high redshift ( > 3) star-forming galaxies challenge our understanding of galaxy formation, as the prevailing view hol…
APOSTLE vs. AURIGA Simulations: How Subgrid Models Shape Milky Way Analogs
Jianhong Hu, Hang Yang, Liang Gao
Despite significant progress in cosmological simulations of galaxy formation, the role of subgrid physics in shaping the detailed properties of galaxies remains incompletely unders…
The capture of halo material by orbiting subhaloes
Hang Yang, Simon D. M. White, Liang Gao
When a dark matter halo falls into a more massive object and becomes a subhalo, it typically loses much of its mass through tidal stripping. The reverse process is also possible in…
The impact of cosmic filaments on the abundance of satellite galaxies
Yuxi Meng, Haonan Zheng, Shihong Liao +9
The impact of cosmic web environments on galaxy properties plays a critical role in understanding galaxy formation. Using the state-of-the-art cosmological simulation IllustrisTNG,…
Where are the Population III star relics in the simulated Milky Way analogues?
Hang Yang, Liang Gao, Qi Guo +3
Using 6 Milky Way analogues with two different numerical resolutions from the Auriga simulation, we investigate the total mass, spatial distribution and kinematics of the Populatio…
The formation and survival of the Milky Way's oldest stellar disk
Maosheng Xiang, Hans-Walter Rix, Hang Yang +3
It remains a mystery when our Milky Way first formed a stellar disk component that survived and maintained its disk structure from subsequent galaxy mergers. We present a study of…
Apostle--Auriga: Effects of stellar feedback subgrid models on the evolution of angular momentum in disc galaxies
Hang Yang, Shihong Liao, Azadeh Fattahi +7
Utilizing the Apostle--Auriga simulations, which start from the same zoom-in initial conditions of Local Group-like systems but run with different galaxy formation subgrid models a…
Kinematic morphology of low-mass galaxies in IllustrisTNG
Guangquan Zeng, Lan Wang, Liang Gao +1
The origin of diverse kinematic morphologies observed in low-mass galaxies is unclear. In this study, we investigate the kinematic morphologies of central galaxies with stellar mas…
Global dynamic scaling relations of HI-rich ultra-diffuse galaxies
Hui-Jie Hu, Qi Guo, Zheng Zheng +4
The baryonic Tully-Fisher relation (BTFR), which connects the baryonic mass of galaxies with their circular velocities, has been validated across a wide range of galaxies, from dwa…
