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 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…
