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 VariableTNG project: Unveiling the physical drivers of galaxy quenching
Ignacio G. Alfaro, Antonio D. Montero-Dorta, Hong Guo +4
Understanding the physical processes that regulate galaxy quenching is a key challenge in galaxy formation and evolution. The VariableTNG (VTNG) project provides a laboratory to in…
Star formation powers optical line emission from the CGM
Huanian Zhang, Lizhi Xie, Zhijie Qu +9
Using integral field spectroscopy, we explore the disk-halo interface, or the inner circumgalactic medium (CGM), of individual galaxies by constructing and analyzing emission-line…
A Potential Link between Nuclear Winds and Cold Gas Outflows on Kiloparsec Scales in Reionization-Era Quasars
Yongda Zhu, Marcia J. Rieke, Luis C. Ho +23
Feedback from accreting supermassive black holes may regulate galaxy evolution, but statistical evidence linking nuclear winds to kiloparsec-scale cold gas outflows remains limited…
Symmetry in Fundamental Parameters of Galaxies on the Star-forming Main Sequence
Zhicheng He, Enci Wang, Luis C. Ho +4
The Star-Forming Main Sequence (SFMS) serves as a critical framework for understanding galaxy evolution, highlighting the relationship between star formation rates (SFR) and stella…
