Star formation and feedback in smoothed particle hydrodynamic simulations – I. Isolated galaxies
We present an analysis of star formation and feedback recipes appropriate for galactic smoothed particle hydrodynamics simulations. Using an isolated Milky Way-like galaxy, we constrain these recipesExpand

Gasoline: a flexible, parallel implementation of TreeSPH
Abstract The key features of the Gasoline code for parallel hydrodynamics with self-gravity are described. Gasoline is an extension of the efficient Pkdgrav parallel N-body code using smoothedExpand

Bulgeless dwarf galaxies and dark matter cores from supernova-driven outflows
For almost two decades the properties of ‘dwarf’ galaxies have challenged the cold dark matter (CDM) model of galaxy formation. Most observed dwarf galaxies consist of a rotating stellar diskExpand

We have performed a high mass and force resolution simulation of an idealized galaxy forming from dissipational collapse of gas embedded in a spherical dark matter halo. The simulation includes starExpand

Fundamental differences between SPH and grid methods
We have carried out a comparison study of hydrodynamical codes by investigating their performance in modelling interacting multiphase fluids. The two commonly used techniques of grid and smoothedExpand

Implications of Stellar Migration for the Properties of Galactic Disks
Stars in disks of spiral galaxies are usually assumed to remain roughly at their birth radii. This assumption is built into decades of modeling of the evolution of stellar populations in our ownExpand

The enrichment of the intergalactic medium with adiabatic feedback – I. Metal cooling and metal diffusion
A study of metal enrichment of the intergalactic medium (IGM) using a series of smooth particle hydrodynamics (SPH) simulations is presented, employing models for metal cooling and the turbulentExpand

Forming disc galaxies in ΛCDM simulations
We used fully cosmological, high-resolution N-body + smooth particle hydrodynamic (SPH) simulations to follow the formation of disc galaxies with rotational velocities between 135 and 270km s -1 in aExpand

Damped Lyman α systems in galaxy formation simulations
We investigate the population of z = 3 damped Lyman alpha systems (DLAs) in a recent series of high resolution galaxy formation simulations. The simulations are of interest because they form at z = 0Expand

The dependence of dark matter profiles on the stellar-to-halo mass ratio: a prediction for cusps versus cores
We use a suite of 31 simulated galaxies drawn from the MaGICC project to investigate the effects of baryonic feedback on the density profiles of dark matter haloes. The sample covers a wide massExpand
