The Graininess of Dark Matter Haloes
Marcel Zemp, Jürg Diemand, Michael Kuhlen +5
We use the recently completed one billion particle Via Lactea II LambdaCDM simulation to investigate local properties like density, mean velocity, velocity dispersion, anisotropy,…
Subhaloes in Scale-Free Cosmologies
P. J. Elahi, R. J. Thacker, L. M. Widrow +1
We explore the dependence of the subhalo mass function on the spectral index n of the linear matter power spectrum using scale-free Einstein-de Sitter simulations with n=-1 and n=-…
Spiral and Bar Instabilities Provoked by Dark Matter Satellites
John Dubinski, Jean-Rene Gauthier, Larry Widrow +1
We explore the secular dynamical evolution of an N-body model of M31 in the presence of a population of 100 dark matter satellites over 10 Gyr. The satellite population has structu…
Dynamical Models for Disk Galaxies with Triaxial Halos
Lawrence M. Widrow
We construct self-consistent dynamical models for disk galaxies with triaxial, cuspy halos. We begin with an equilibrium, axisymmetric, disk-bulge-halo system and apply an artifici…
