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…
The survival and disruption of CDM micro-haloes: implications for direct and indirect detection experiments
Tobias Goerdt, Oleg Y. Gnedin, Ben Moore +2
If the dark matter particle is a neutralino then the first structures to form are cuspy cold dark matter (CDM) haloes collapsing after redshifts z ~ 100 in the mass range 10^{-6} -…
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…
Dynamical friction in constant density cores: a failure of the Chandrasekhar formula
J. I. Read, Tobias Goerdt, Ben Moore +3
Using analytic calculations and N-body simulations we show that in constant density (harmonic) cores, sinking satellites undergo an initial phase of very rapid (super-Chandrasekhar…
An optimum time-stepping scheme for N-body simulations
Marcel Zemp, Joachim Stadel, Ben Moore +1
We present a new time-stepping criterion for N-body simulations that is based on the true dynamical time of a particle. This allows us to follow the orbits of particles correctly i…
