The colours of satellite galaxies in groups and clusters (2008)
Journal Article
Font, A., Bower, R., McCarthy, I., Benson, A., Frenk, C., Helly, J., …Cole, S. (2008). The colours of satellite galaxies in groups and clusters. Monthly Notices of the Royal Astronomical Society, 389(4), 1619-1629. https://doi.org/10.1111/j.1365-2966.2008.13698.x

Current models of galaxy formation predict satellite galaxies in groups and clusters that are redder than observed. We investigate the effect on the colours of satellite galaxies produced by the ram-pressure stripping of their hot-gaseous atmospheres...

The redshift dependence of the structure of massive Λ cold dark matter haloes (2008)
Journal Article
Gao, L., Navarro, J., Cole, S., Frenk, C., White, S., Springel, V., …Neto, A. (2008). The redshift dependence of the structure of massive Λ cold dark matter haloes. Monthly Notices of the Royal Astronomical Society, 387(2), 536-544. https://doi.org/10.1111/j.1365-2966.2008.13277.x

We use two very large cosmological simulations to study how the density profiles of relaxed Λ cold dark matter dark haloes depend on redshift and on halo mass. We confirm that these profiles deviate slightly but systematically from the NFW form and a... Read More about The redshift dependence of the structure of massive Λ cold dark matter haloes.

The galaxy power spectrum: precision cosmology from large-scale structure? (2008)
Journal Article
Sánchez, A., & Cole, S. (2008). The galaxy power spectrum: precision cosmology from large-scale structure?. Monthly Notices of the Royal Astronomical Society, 385(2), 830-840. https://doi.org/10.1111/j.1365-2966.2007.12787.x

Published galaxy power spectra from the two-degree field galaxy redshift survey (2dFGRS) and Sloan Digital Sky Survey (SDSS) are not in good agreement. We revisit this issue by analysing both the 2dFGRS and SDSS Data Release 5 (DR5) catalogues using... Read More about The galaxy power spectrum: precision cosmology from large-scale structure?.

Generating dark matter halo merger trees (2008)
Journal Article
Parkinson, H., Cole, S., & Helly, J. (2008). Generating dark matter halo merger trees. Monthly Notices of the Royal Astronomical Society, 383(2), 557-564. https://doi.org/10.1111/j.1365-2966.2007.12517.x

We present a new Monte Carlo algorithm to generate merger trees describing the formation history of dark matter haloes. The algorithm is a modification of the algorithm of Cole et al. used in the galform semi-analytic galaxy formation model. As such,... Read More about Generating dark matter halo merger trees.
