    VLT/FORS1 spectrophotometry of the first planetary nebula discovered in the Phoenix dwarf galaxy
    Context: A planetary nebula (PN) candidate was discovered during FORS imaging of the Local Group dwarf galaxy Phoenix. Aims: We use this PN to complement...

    VLTI/GRAVITY interferometric measurements of the innermost dust structure sizes around active galactic nuclei
    We present new Very Large Telescope Interferometer (VLTI)/GRAVITY near-infrared interferometric measurements of the angular size of the innermost hot dust...

    Void Statistics in Large Galaxy Redshift Surveys: Does Halo Occupation of Field Galaxies Depend on Environment?
    We use measurements of the projected galaxy correlation function wp(rp) and galaxy void statistics to test whether the galaxy content of halos of fixed mass is...

    VV124 (UGC4879): a new transitional dwarf galaxy in the periphery of the Local Group
    We present the first photometry of individual stars within VV124 (UGC4879) and find that this is the most isolated dwarf galaxy in the periphery of the Local...

    WALLABY pilot survey: H I gas disc truncation and star formation of galaxies falling into the Hydra I cluster
    We present results from our analysis of the Hydra I cluster observed in neutral atomic hydrogen (H I) as part of the Widefield ASKAP L-band Legacy All-sky Blind...

    WALLABY pre-pilot survey: two dark clouds in the vicinity of NGC 1395
    We present the Australian Square Kilometre Array Pathfinder (ASKAP) WALLABY pre-pilot observations of two 'dark' H I sources (with H I masses of a few times 10...

    Warm molecular and ionized gas kinematics in the type-2 quasar J0945+1737
    We analyse Near-Infrared Integral Field Spectrograph (NIFS) observations of the type-2 quasar (QSO2) SDSS J094521.33+173753.2 to investigate its warm molecular...

    Warps and correlations with intrinsic parameters of galaxies in the visible and radio
    From a comparison of the different parameters of warped galaxies in the radio, and especially in the visible, we find that: a) No large galaxy (large mass or...
