The VariableTNG project: mass-dependent regulation of galaxy morphology by baryonic feedback
Yikai Liu, Hong Guo, Volker Springel +3
Galaxy morphology is shaped by both assembly history and baryonic processes, but their relative roles remain uncertain. We use the VariableTNG (VTNG) simulation suite to investigat…
The VariableTNG project: how baryonic mechanisms shape galaxy properties
Kexin Liu, Hong Guo, Luis C. Ho +3
We use 50 Sobol-sampled VariableTNG simulations, varying eight subgrid parameters at fixed cosmology and initial conditions, to determine which baryonic processes regulate galaxies…
The origin of lopsided satellite galaxy distribution around isolated systems in MillenniumTNG
Yikai Liu, Peng Wang, Hong Guo +4
Dwarf satellites in galaxy groups are distributed in an anisotropic and asymmetric manner, which is called the ``lopsided satellite distribution''. This lopsided signal has been ob…
EASE: An Easily-Customized Annotation System Powered by Efficiency Enhancement Mechanisms
Naihao Deng, Yikai Liu, Mingye Chen +5
The performance of current supervised AI systems is tightly connected to the availability of annotated datasets. Annotations are usually collected through annotation tools, which a…
