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 recipes
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 smoothed
The Santa Barbara cluster comparison project: A comparison of cosmological hydrodynamics solutions
We have simulated the formation of an X-ray cluster in a cold dark matter universe using 12 different codes. The codes span the range of numerical techniques and implementations currently in use,
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 smoothed
Bulgeless dwarf galaxies and dark matter cores from supernova-driven outflows
Hydrodynamical simulations in a framework assuming the presence of CDM and a cosmological constant are reported in which the inhomogeneous interstellar medium is resolved and the analogues of dwarf galaxies—bulgeless and with shallow central dark-matter profiles—arise naturally in these simulations.
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 star
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 own
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 turbulent
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 a
The impact of mergers on relaxed X-ray clusters – I. Dynamical evolution and emergent transient structures
We report on the analysis of a suite of smoothed particle hydrodynamics simulations (incorporating cooling and star formation) of mergers involving idealized X-ray clusters whose initial conditions
