MOSEL and IllustrisTNG: Massive Extended Galaxies at z=2 Quench Later Than Normal-size Galaxies
Anshu Gupta, Kim-Vy Tran, Annalisa Pillepich +4
Using the TNG100 (100 Mpc)^3 simulation of the IllustrisTNG project, we demonstrate a strong connection between the onset of star formation quenching and the stellar size of galaxi…
Towards a consistent framework of comparing galaxy mergers in observations and simulations
L. Wang, W. J. Pearson, V. Rodriguez-Gomez
Aims. We aim to perform consistent comparisons between observations and simulations on the mass dependence of the galaxy major merger fraction at low redshift over an unprecedented…
The stellar halos of ETGs in the IllustrisTNG simulations: II. Accretion, merger history, and dark halo connection
C. Pulsoni, O. Gerhard, M. Arnaboldi +5
Stellar halos in early-type galaxies (ETGs) are shaped by their accretion and merger histories. We use a sample of 1114 ETGs in the TNG100 simulation with stellar masses $10^{10.3}…
Quenched fractions in the IllustrisTNG simulations: the roles of AGN feedback, environment, and pre-processing
Martina Donnari, Annalisa Pillepich, Gandhali D. Joshi +8
We use the IllustrisTNG simulations to show how the fractions of quenched galaxies vary across different environments and cosmic time, and to quantify the role AGN feedback and pre…
The Morphology-Density relationship in 1<z<2 clusters
Elizaveta Sazonova, Katherine Alatalo, Jennifer Lotz +8
The morphology-density relationship states that dense cosmic environments such as galaxy clusters have an overabundance of quiescent elliptical galaxies, but it is unclear at which…
The relationship between fine galaxy stellar morphology and star formation activity in cosmological simulations: a deep learning view
Lorenzo Zanisi, Marc Huertas-Company, Francois Lanusse +10
Hydrodynamical simulations of galaxy formation and evolution attempt to fully model the physics that shapes galaxies. The agreement between the morphology of simulated and real gal…
