Measuring the three-dimensional shear from simulation data, with applications to weak gravitational lensing
H. M. P. Couchman, Andrew J. Barber, Peter A. Thomas
We have developed a new three-dimensional algorithm, based on the standard PM method, for computing deflections due to weak gravitational lensing. We compare the results of thi…
Smoothed Particle Hydrodynamics in cosmology: a comparative study of implementations
R. J. Thacker, E. R. Tittley, F. R. Pearce +2
We analyse the performance of twelve different implementations of Smoothed Particle Hydrodynamics (SPH) using seven tests designed to isolate key hydrodynamic elements of cosmologi…
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…
The Bispectrum as a Signature of Gravitational Instability in Redshift-Space
Roman Scoccimarro, H. M. P. Couchman, Joshua A. Frieman
The bispectrum provides a characteristic signature of gravitational instability that can be used to probe the Gaussianity of the initial conditions and the bias of the galaxy distr…
A New Parallel P3M Code for Very Large-Scale Cosmological Simulations
Tom MacFarland, H. M. P. Couchman, F. R. Pearce +1
We have developed a parallel Particle-Particle, Particle-Mesh (P3M) simulation code for the Cray T3E parallel supercomputer that is well suited to studying the time evolution of sy…
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…
