Introducing RAFIKI: Refining AGN Feedback in Kinetic Implementations

Skylar Grayson, Evan Scannapieco, Romeel Davé +2

Modern cosmological simulations have now matured to the point of reproducing the evolution of realistic galaxy populations across cosmic time. These simulations rely on feedback fr…

Forged by Feedback: Stellar Properties of Brightest Group Galaxies in Cosmological Simulations

Ruxin Barré, Arif Babul, Ghassem Gozaliasl +7

We investigate how different galaxy formation models impact the stellar properties of brightest group galaxies (BGGs) in four cosmological simulations: ROMULUS, SIMBA, SIMBA-C, and…

Core to Cosmic Edge: SIMBA-C's New Take on Abundance Profiles in the Intragroup Medium at z = 0

Aviv Padawer-Blatt, Zhiwei Shao, Renier T. Hough +9

We employ the SIMBA-C cosmological simulation to study the impact of its upgraded chemical enrichment model (Chem5) on the distribution of metals in the intragroup medium (IGrM). 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…

\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…
