The history of stellar metallicity in a simulated disc galaxy
O. N. Snaith, J. Bailin, B. K. Gibson +5
We explore the chemical distribution of stars in a simulated galaxy. Using simulations of the same initial conditions but with two different feedback schemes (MUGS and MaGICC), we…
Weighing the Galactic disk using the Jeans equation: lessons from simulations
G. N. Candlish, R. Smith, C. Moni Bidin +1
Using three-dimensional stellar kinematic data from simulated galaxies, we examine the efficacy of a Jeans equation analysis in reconstructing the total disk surface density, inclu…
Chemodynamics of a Simulated Disc Galaxy: Initial Mass Functions and SNIa Progenitors
C. G. Few, S. Courty, B. K. Gibson +2
We trace the formation and advection of several elements within a cosmological adaptive mesh refinement simulation of an L* galaxy. We use nine realisations of the same initial con…
The Role of Feedback in Shaping the Structure of the Interstellar Medium
A. P. Walker, B. K. Gibson, K. Pilkington +5
We present an analysis of the role of feedback in shaping the neutral hydrogen (HI) content of simulated disc galaxies. For our analysis, we have used two realisations of two separ…
Phase mixing due to the Galactic potential: steps in the position and velocity distributions of popped star clusters
G. N. Candlish, R. Smith, M. Fellhauer +3
As star clusters are expected to form with low star formation efficiencies, the gas in the cluster is expelled quickly and early in their development: the star cluster "pops." This…
The MaGICC Baryon Cycle: The Enrichment History of Simulated Disc Galaxies
C. B. Brook, G. Stinson, B. K. Gibson +4
Using cosmological galaxy formation simulations from the MaGICC project, spanning more than three magnitudes in stellar mass (~10^7-3x10^{10} Msun), we trace the baryonic cycle of…
Properties of simulated Milky Way-mass galaxies in loose group and field environments
C. G. Few, B. K. Gibson, S. Courty +3
We test the validity of comparing simulated field disk galaxies with the empirical properties of systems situated within environments more comparable to loose groups, including the…
Thin disc, Thick Disc and Halo in a Simulated Galaxy
C. B. Brook, G. S. Stinson, B. K. Gibson +8
Within a cosmological hydrodynamical simulation, we form a disc galaxy with sub- components which can be assigned to a thin stellar disc, thick disk, and a low mass stellar halo vi…
Metallicity Gradients in Disks: Do Galaxies Form Inside-Out?
K. Pilkington, C. G. Few, B. K. Gibson +13
We examine radial and vertical metallicity gradients using a suite of disk galaxy simulations, supplemented with two classic chemical evolution approaches. We determine the rate of…
Chemical and Dynamical Properties of the Stellar Halo
C. B. Brook, D. Kawata, H. Martel +2
The difference in density profiles of the contributions from different density peaks to dark matter halos results in certain expectations about the Milky Way's stellar halo. We cut…
The Spatial Distribution of the Galactic First Stars II: SPH Approach
Chris B. Brook, Daisuke Kawata, Evan Scannapieco +2
We use cosmological, chemo-dynamical, smoothed particle hydrodynamical simulations of Milky-Way-analogue galaxies to find the expected present-day distributions of both metal-free…
