    The SDSS-III Baryon Oscillation Spectroscopic Survey: The Quasar Luminosity Function from Data Release Nine
    We present a new measurement of the optical quasar luminosity function (QLF), using data from the Sloan Digital Sky Survey-III: Baryon Oscillation Spectroscopic...

    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 Size Distribution of Excursion Sets and the Cosmic Mass Function
    We obtain the probability distribution for the volume of excursion sets in a three-dimensional Gaussian field, in order to develop the approximation to the...

    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...

    The spectral index-flux density relation for extragalactic radio sources selected at metre and decametre wavelengths
    We use the recent releases of sensitive VLA/LOFAR large-area surveys at 340 MHz and 54 MHz, in conjunction with the 1.4 GHz NVSS, to accurately determine the...
