    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...

    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...

    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...

    The HST/ACS Coma Cluster Survey - VI. Colour gradients in giant and dwarf early-type galaxies
    Using deep, high-spatial-resolution imaging from the Hubble Space Telescope/Advanced Camera for Surveys (HST/ACS) Coma Cluster Treasury Survey, we determine...

    The HST/ACS Coma Cluster Survey - VII. Structure and assembly of massive galaxies in the centre of the Coma cluster
    We constrain the assembly history of galaxies in the projected central 0.5 Mpc of the Coma cluster by performing structural decomposition on 69 massive (M⋆ ≥...

    The HST/ACS Coma Cluster Survey - X. Nuclear star clusters in low-mass early-type galaxies: scaling relations
    We present scaling relations between structural properties of nuclear star clusters and their host galaxies for a sample of early-type dwarf galaxies observed...

    The HST/ACS Coma Cluster Survey. II. Data Description and Source Catalogs
    The Coma cluster, Abell 1656, was the target of an HST-ACS Treasury program designed for deep imaging in the F475W and F814W passbands. Although our survey was...
