We examine the properties of the galaxies and dark matter haloes residing in the cluster infall region surrounding the simulated _ cold dark matter galaxy cluster studied by Elahi et al. at z = 0. The 1.1 × 1015 h−1M_ galaxy cluster has been simulate... Read More about nIFTy galaxy cluster simulations – V. Investigation of the cluster infall region.

© 2016 IOP Publishing Ltd and Sissa Medialab srl. Future galaxy surveys require one percent precision in the theoretical knowledge of the power spectrum over a large range including very nonlinear scales. While this level of accuracy is easily obtain... Read More about Matter power spectrum and the challenge of percent accuracy.

Merger trees are routinely used to follow the growth and merging history of dark matter haloes and subhaloes in simulations of cosmic structure formation. Srisawat et al. compared a wide range of merger-tree-building codes. Here we test the influence... Read More about Sussing merger trees: stability and convergence.
