Journal ArticleDOI
The Emergence of the Thick Disk in a Cold Dark Matter Universe
TL;DR: In this article, the chemodynamic galaxy formation code, GCD+, is used to simulate the formation of a disk galaxy with a thick disk component, which is consistent with observations of both the Milky Way and extragalactic thick disks.
Journal ArticleDOI
Strangulation in Galaxy Groups
TL;DR: In this paper, the authors used a cosmological chemodynamical simulation to study how the group environment impacts the star formation (SF) properties of disk galaxies and found that the strangulation mechanism works even in low-mass groups, providing an explanation for the lower SF rates in group galaxies relative to galaxies in the field.
Journal ArticleDOI
GCD+: a new chemodynamical approach to modelling supernovae and chemical enrichment in elliptical galaxies
Daisuke Kawata,Brad K. Gibson +1 more
TL;DR: In this paper, the authors developed a new galactic chemo-dynamical evolution code, called GCD+, for studies of galaxy formation and evolution, which includes selfgravity, hydrodynamics, radiative cooling, star formation, supernova feedback, and metal enrichment.
Journal ArticleDOI

TL;DR: In this paper, a cosmological hydrodynamical simulation of a disc galaxy with subcomponents can be assigned to a thin stellar disc, a thick disk, and a low mass stellar halo via a chemical decomposition.
Journal ArticleDOI
Metallicity gradients in disks - Do galaxies form inside-out?

Couchman,Jeremy Bailin,James Wadsley +24 more
TL;DR: In this article, the authors examined radial and vertical metallicity gradients using a suite of disk galaxy hydrodynamical simulations, supplemented with two classic chemical evolution approaches to reconcile the differences existing between extant models and observations within the canonical “inside-out” disk growth paradigm.
