Building up the Stellar Halo of the Milky Way
Amina Helmi, Simon D. M. White
We study numerical simulations of satellite galaxy disruption in a potential resembling that of the Milky Way. Our goal is to assess whether a merger origin for the stellar halo wo…
Velocity Fields from IRAS-PSCz survey
E. Branchini, C. S. Frenk L. Teodoro, I. Schmoldt +9
We present a self-consistent nonparametric model of the cosmic velocity field based on the spatial distribution of IRAS galaxies in the recently completed all-sky PSC redshift s…
The Formation and Evolution of Disk Galaxies
Shude Mao, H. J. Mo, Simon D. M. White
We review some of our recent progress in modelling the formation of disk galaxies in the framework of hierarchical structure formation. Our model is not only consistent with the lo…
Galaxy Clusters in the Hubble Volume Simulations
Joerg M. Colberg, Simon D. M. White, Thomas J. MacFarland +8
We report on analyses of cluster samples obtained from the Hubble Volume Simulations. These simulations, an model named CDM and a flat low model with a cosmological co…
Peculiar Velocities of Galaxy Clusters
J. M. Colberg, S. D. M. White, T. J. MacFarland +5
We investigate the peculiar velocities predicted for galaxy clusters by theories in the cold dark matter family. A widely used hypothesis identifies rich clusters with high peaks o…
Numerical Investigations of Weak Lensing by Large-Scale Structure
Bhuvnesh Jain, Uros Seljak, Simon White
We use numerical simulations of ray tracing through N-body simulations to investigate weak lensing by large-scale structure. These are needed for testing the analytic predictions o…
