    The extended 'stellar halo' of the Ursa Minor dwarf galaxy
    Stellar candidates in the Ursa Minor (UMi) dwarf galaxy have been found using a new Bayesian algorithm applied to Gaia EDR3 data. Five of these targets are...

    The extended narrow line region of NGC 4151
    We present high quality long-slit spectra of the extended narrow line region (ENLR) near the nucleus of NGC 4151. We have used these data to map the spatial...

    The extended nebulosity in the radio galaxy 3C 227
    3C 227 (z = 0.085) exhibits one of the more spectacular extended nebulosities to be found among active galaxies at moderate redshifts. The gas can be traced to...

    The extended structure of the dwarf irregular galaxy Sagittarius
    We present a detailed study of the stellar and H i structure of the dwarf irregular galaxy Sagittarius. We use new deep and wide field photometry to trace the...
