    The rates and modes of gas accretion on to galaxies and their gaseous haloes
    We study the rate at which gas accretes on to galaxies and haloes and investigate whether the accreted gas was shocked to high temperatures before reaching a...

    The Redshift Distribution of Flat-Spectrum Radio Sources
    The redshift distribution of flat-spectrum radio sources with 5 GHz flux densities S5>~5 mJy is a key component in using current radio lens surveys to probe the...

    The SDSS-III Baryonic Oscillation Spectroscopic Survey: constraints on the integrated Sachs-Wolfe effect
    In the context of the study of the integrated Sachs-Wolfe (ISW) effect, we construct a template of the projected density distribution up to redshift z ≃ 0.7 by...

    The spatial distribution of galaxies within the cosmic microwave background cold spot in the Corona Borealis supercluster
    We study the spatial distribution and colours of galaxies within the region covered by the cold spot in the cosmic microwave background recently detected by the...
