Journal ArticleDOI
Gasoline2: a modern smoothed particle hydrodynamics code
TL;DR: The Gasoline2 as mentioned in this paper is the most recent version of the Gasoline code for parallel hydrodynamics and gravity with identical hydroynamics to the Changa code.
Journal ArticleDOI
Faint dwarfs as a test of DM models: WDM versus CDM

TL;DR: In this article, the authors used high resolution Hydro+N-Body cosmological simulations to compare the assembly and evolution of a small field dwarf (stellar mass ∼ 10 6 7 M, total mass 10 10 M) indominated CDM and 2keV WDM cosmologies and found that star for-mation (SF) in the WDM model is reduced and delayed by 1-2 Gyr relative to the CDM model, independently of the details of SF and feedback.
Journal ArticleDOI
Chaos and variance in galaxy formation
TL;DR: In this article, the authors examine the importance of stochasticity due to discreteness noise, variations in merger timings and how self-regulation moderates the effects of this stochasticallyity.
Journal ArticleDOI
Heart of darkness: the influence of galactic dynamics on quenching star formation in galaxy spheroids
TL;DR: In this paper, a suite of hydrodynamical simulations of isolated galaxies containing a spheroid was performed to investigate the impact of these morphological components on star formation, and the most bulge-dominated galaxies showed the strongest deviation from the main sequence.
Journal ArticleDOI
