Redshift Evolution of Galaxy Group X-ray Properties in Simba
Dylan Robson, Romeel Davé
We examine the evolution of intragroup gas X-ray scaling relations for group-sized halos () in the Simba galaxy formation simulation. X-ray luminosit…
The origin of galaxy colour bimodality in the scatter of the Stellar-to-Halo Mass Relation
Weiguang Cui, Romeel Davé, John A. Peacock +2
Recent observations reveal that, at a given stellar mass, blue galaxies tend to live in haloes with lower mass while red galaxies live in more massive host haloes. The physical dri…
IQ Collaboratory III: The Empirical Dust Attenuation Framework -- Taking Hydrodynamical Simulations with a Grain of Dust
ChangHoon Hahn, Tjitske K. Starkenburg, Daniel Anglés-Alcázar +8
We present the Empirical Dust Attenuation (EDA) framework -- a flexible prescription for assigning realistic dust attenuation to simulated galaxies based on their physical properti…
An Orientation Bias in Observations of Submillimetre Galaxies
C. C. Lovell, J. E. Geach, R. Davé +5
Recent high-resolution interferometric images of submillimetre galaxies (SMGs) reveal fascinatingly complex morphologies. This raises a number of questions: how does the relative o…
A New Model For Including Galactic Winds in Simulations of Galaxy Formation II: Implementation of PhEW in Cosmological Simulations
Shuiyao Huang, Neal Katz, J'Neil Cottle +3
Although galactic winds play a critical role in regulating galaxy formation, hydrodynamic cosmological simulations do not resolve the scales that govern the interaction between win…
Quenching and the UVJ diagram in the SIMBA cosmological simulation
Hollis B. Akins, Desika Narayanan, Katherine E. Whitaker +5
Over the past decade, rest-frame color-color diagrams have become popular tools for selecting quiescent galaxies at high redshift, breaking the color degeneracy between quiescent a…
