    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...
  • Publication
    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...
  • Publication
    The nature of comet-asteroid transition object (3200) Phaethon
    Context: The study of asteroids that present sporadic cometary activity is of fundamental importance to address several astronomical problems including the end...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
  • Publication
    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...
  • Publication
    The nature of HH 223 from long-slit spectroscopy
    Context: HH 223 is a knotty, undulating nebular emission of ˜30 arcsec length found in the L723 star-forming region. It lies projected onto the largest...
