    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...

    The nature of arms in spiral galaxies. IV. Symmetries and asymmetries
    A Fourier analysis of the intensity distribution in the planes of nine spiral galaxies is performed. In terms of the arm classification scheme of cite[Elmegreen...

    The Nature of Close Companions of the BL Lacertae Objects 1ES 0502+675 and 1ES 1440+122
    We report on deep radio images and optical spectroscopy of two BL Lac objects that have very close compact companions. The two targets, 1ES 0502+675 and 1ES...

    The Nature of Dust in Compact Galactic Planetary Nebulae from Spitzer Spectra
    We present the Spitzer/Infrared Spectrograph (IRS) spectra of 157 compact Galactic planetary nebulae (PNe). These young PNe provide insight on the effects of...

    The nature of faint radio galaxies at high redshifts
    We present spectra and near-infrared images of a sample of faint radio sources initially selected as promising high-redshift radio galaxy (HzRG) candidates. We...

    The Nature of Fossil Galaxy Groups: Are They Really Fossils?
    We use SDSS-DR4 photometric and spectroscopic data out to redshift z ~ 0.1 combined with ROSAT All Sky Survey X-ray data to produce a sample of 25 fossil groups...

    The nature of giant clumps in high-z discs: a deep-learning comparison of simulations and observations
    We use deep learning to explore the nature of observed giant clumps in high-redshift disc galaxies, based on their identification and classification in...
