    The Nature of Growing Bulges Within z < 1.3 Galaxy Disks in the GOODS-N Field
    We analyze central surface brightness μ0, nuclear and global colors of intermediate redshift disk galaxies. On an apparent-diameter-limited sample of 398...

    The nature of late-type spiral galaxies: structural parameters, optical and near-infrared colour profiles and dust extinction
    We analyse V- and H-band surface photometry of a sample of 18 Sb-Sd galaxies. Combining high-resolution Hubble Space Telescope (HST) images with ground-based...

    The Nature of the Antlia Galaxy: A New Dwarf Irregular in the Outskirts of the Local Group.
    The Antlia dwarf galaxy, recently found to be a possible local Group member, is analyzed using VI photometry. The galaxy is resolved into a large number of...

    The nuclear activity and central structure of the elliptical galaxy NGC 5322
    We have analysed a new high-resolution e-MERLIN 1.5 GHz radio continuum map together with HST and SDSS imaging of NGC 5322, an elliptical galaxy hosting radio...

    The nuclear and extended mid-infrared emission of Seyfert galaxies
    We present subarcsecond resolution mid-infrared (MIR) images obtained with 8-10 m-class ground-based telescopes of a complete volume-limited (DL 40 Mpc) sample...

    The Nuclear Infrared Emission of Low-luminosity Active Galactic Nuclei
    We present high-resolution mid-infrared (MIR) imaging, nuclear spectral energy distributions (SEDs), and archival Spitzer spectra for 22 low-luminosity active...

    The optical morphologies of the 2 Jy sample of radio galaxies: evidence for galaxy interactions
    We present deep Gemini Multi-Object Spectrograph South (GMOS-S)/Gemini optical broad-band images for a complete sample of 46 southern 2 Jy radio galaxies at...

    The optical properties of low redshift radio galaxies
    We present morphological and photometric properties of 79 low redshift (z=-24.0 with a clear trend for FRI sources to be ~ 0.5 mag brighter than FRII galaxies...

    The Orbit and Companion of PSR J1622-0315: Variable Asymmetry and a Massive Neutron Star
    The companion to PSR J1622-0315, one of the most compact known redback millisecond pulsars, shows extremely low irradiation despite its short orbital period. We...
