We combine a semi-analytical model of galaxy formation with a very large simulation which follows the growth of a large-scale structure in a Λ cold dark matter (ΛCDM) universe to predict the clustering of Lyα emitters. We find that the clustering str... Read More about The clustering of Lyα emitters in a ΛCDM Universe.

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...

A population of faint extended line emitters and the host galaxies of optically thick QSO absorption systems (2008)

We have conducted a long-slit search for low surface brightness Lyα emitters at redshift 2.67 < z < 3.75. A 92 hr long exposure with the ESO VLT FORS2 instrument down to a 1 σ surface brightness detection limit of 8 × 10−20 erg cm−2 s−1 arcsec−2 per...

We use an extremely large volume (2.4 h−3Gpc3), high-resolution N-body simulation to measure the higher order clustering of dark matter haloes as a function of mass and internal structure. As a result of the large simulation volume and the use of a n... Read More about The assembly bias of dark matter haloes to higher orders.

Luminous red galaxies in hierarchical cosmologies (2008)
Journal Article

Luminous red galaxies (LRGs) are much rarer and more massive than L* galaxies. Coupled with their extreme colours, LRGs therefore provide a demanding testing ground for the physics of massive galaxy formation. We present the first self-consistent pre...
