    The HIPASS catalogue - III. Optical counterparts and isolated dark galaxies
    We present the largest catalogue to date of optical counterparts for HI radio-selected galaxies, HOPCAT. Of the 4315 HI radio-detected sources from the HI...

    The host galaxies of BL Lac objects in the near-infrared
    We present the results of near-infrared H band (1.65 μm) imaging of 11 BL Lac objects with redshifts ranging from z = 0.05 to 0.9. We are able to clearly detect...

    The Host Galaxies of Radio-loud Active Galactic Nuclei: The Black Hole-Galaxy Connection
    We have studied the host galaxies of a sample of radio-loud active galactic nuclei (AGNs) spanning more than 4 decades in the energy output of the nucleus. The...

    The Host Galaxy of the Lensed Quasar Q0957+561
    Infrared images of the Q0957+561 gravitational lens obtained with the Hubble Space Telescope show two large (~5") lensed images of the zs=1.41 quasar host...

    The host galaxy of the γ-ray-emitting narrow-line Seyfert 1 galaxy PKS 1502+036
    The detection of γ-ray emission from narrow-line Seyfert 1 galaxies (NLSy1) has challenged the idea that large black hole (BH) masses (≥108 M⊙) are needed to...

    The host in blue compact galaxies.. Structural properties and scaling relations
    Aims: We characterise the underlying stellar host in a sample of 20 blue compact galaxies (BCGs), by fitting their two-dimensional light distributions. Their...
  • Publication
    The HST/ACS Coma Cluster Survey - III. Structural parameters of galaxies using single Sérsic fits
    We present a catalogue of structural parameters for 8814 galaxies in the 25 fields of the Hubble Space Telescope/ACS Coma Treasury Survey. Parameters from...
  • Publication
    The HST/ACS Coma Cluster Survey - V. Compact stellar systems in the Coma Cluster
    The Hubble Space Telescope/Advanced Camera for Surveys (HST/ACS) Coma Cluster Treasury Survey is a deep two-passband imaging survey of the nearest very rich...
