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.…
Hyenas: X-ray Bubbles and Cavities in the Intra-Group Medium
Fred J. Jennings, Arif Babul, Romeel Dave +2
We investigate the role of the Simba feedback model on the structure of the Intra-Group Medium (IGrM) in the new Hyenas suite of cutting-edge cosmological zoom-in simulations. Usin…
The HYENAS project: a prediction for the X-ray undetected galaxy groups
Weiguang Cui, Fred Jennings, Romeel Dave +2
Galaxy groups contain the majority of bound mass with a significant portion of baryons due to the combination of halo mass and abundance (Cui 2024). Hence they serve as a crucial m…
\texttt{Simba}-\texttt{C}: the evolution of the thermal and chemical properties in the intragroup medium
Renier T. Hough, Zhiwei Shao, Weiguang Cui +5
The newly updated \texttt{GIZMO} and \texttt{Simba} based simulation, \texttt{Simba-C}, with its new stellar feedback, chemical enrichment, and recalibrated AGN feedback, allows fo…
Populating Galaxies Into Halos Via Machine Learning on the Simba Simulation
Pratyush Kumar Das, Romeel Davé, Weiguang Cui
We present a machine-learning framework, Machine Inferred Galaxy (MIG), to populate dark-matter haloes with galaxies in N-body simulations. MIG predicts stellar mass (), st…
The Effect of AGN Feedback on the Lyman-α Forest Signature of Galaxy Protoclusters at z~2.3
Chenze Dong, Khee-Gan Lee, Romeel Davé +2
The intergalactic medium (IGM) in the vicinity of galaxy protoclusters are interesting testbeds to study complex baryonic effects such as gravitational shocks and feedback. Here, w…
The Nature and Evolution of Early Massive Quenched Galaxies in the Simba-C Simulation
Jakub Szpila, Romeel Davé, Douglas Rennehan +2
We examine the nature, origin, and fate of early () massive () quenched galaxies (EQGs) in a new run of the Simba-C galaxy…
