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…
Investigating the residuals in the relation using the SIMBA cosmological simulation
Wenlin Ma, Weiguang Cui, Romeel Davé +2
We study the scaling relation between the black hole and stellar mass (), diagnosing the residual () in this relation to understand the…
Disparate Effects of Circumgalactic Medium Angular Momentum in IllustrisTNG and SIMBA
Kexin Liu, Hong Guo, Sen Wang +4
In this study, we examine the role of circumgalactic medium (CGM) angular momentum () on star formation in galaxies, whose influence is currently not well understood.…
