Fundamental differences between SPH and grid methods
Oscar Agertz, Ben Moore, Joachim Stadel +17
We have carried out a hydrodynamical code comparison study of interacting multiphase fluids. The two commonly used techniques of grid and smoothed particle hydrodynamics (SPH) show…
Dark Satellites and Cosmic Reionization
Andrea V. Maccio', Ben Moore, Joachim Stadel +1
A possible explanation of the present discrepancy between the abundance of galactic subhaloes predicted by N-Body simulations with those observed in the Local Group is presented. W…
Concentration, Spin and Shape of Dark Matter Haloes: Scatter and the Dependence on Mass and Environment
Andrea V. Maccio', Aaron A. Dutton, Frank C. van den Bosch +3
We use a series of cosmological N-body simulations for a flat LCDM cosmology to investigate the properties of dark matter haloes in the mass range 3.0e9-3.0e13 Msun. These properti…
An alternative to grids and glasses: Quaquaversal pre-initial conditions for N-body simulations
Steen H. Hansen, Oscar Agertz, Michael Joyce +3
N-body simulations sample their initial conditions on an initial particle distribution, which for cosmological simulations is usually a glass or grid, whilst a Poisson distribution…
