    The nature and origin of substructure in the outskirts of M31 - II. Detailed star formation histories
    While wide-field surveys of M31 have revealed much substructure at large radii, understanding the nature and origin of this material is not straightforward from...

    The Nature and Size of the Optical Continuum Source in QSO 2237+0305
    From the peak of a gravitational microlensing high-magnification event in the A component of QSO 2237+0305, which was accurately monitored by the Gravitational...

    The nature and structure of the emission line nebula K3-35: a very young planetary nebula with precessing bipolar jet-like outflows?
    We present Hα, [NII]6583 and 6-cm continuum images of the emission line nebula K3-35. The optical images reveal an extended nebula (size ~=11x9arcsec^2 in [NII]...

    The nature of 500 micron risers - II. Multiplicities and environments of sub-mm faint dusty star-forming galaxies
    We present Submillimeter Common User Bolometer Array 2 (SCUBA-2) and Submillimeter Array (SMA) follow-up observations of four candidate high-redshift dusty star...
  • Publication
    The nature of 500 micron risers I: SMA observations
    We present SMA observations at resolutions from 0.35 to 3 arcsec of a sample of 34 candidate high redshift dusty star forming galaxies (DSFGs). These sources...

    The Nature of 500 micron Risers III: a small complete sample
    Herschel surveys have found large numbers of sources with red far-IR colours, and spectral energy distributions (SEDs) rising from 250 to 500 µm: 500 risers...

    The nature of arms in spiral galaxies. II. The sample
    We present here the results of an imaging study of eight grand-design and two intermediate-arm galaxies, based on CCD observations in U, B, V, R and I. We give...

    The nature of arms in spiral galaxies. I - Azimuthal colour profiles of NGC 7479 and NGC 1832
    A set of parameters to characterize azimuthal profiles of galaxies is proposed and applied to the spiral structure of the galaxies NGC 1832 and NGC 7479...

    The nature of arms in spiral galaxies. III. Azimuthal profiles
    In this paper we analyse the structure of a small sample of galaxies using a set of CCD images in standard photometric bands presented in a previous paper (del...
