    The origin of the CMR in Virgo
    We study the origin of the colour magnitude relation (CMR) in the Virgo cluster. The CMR could be either caused by a variation of the mean stellar metallicity...

    The origin of the ionization of the diffuse interstellar medium in spiral galaxies. I. Photometric measurements
    We present a complete study of the diffuse ionized gas (DIG) in a sample of six spiral galaxies (NGC 157, NGC 3359, NGC 3631, NGC 6764, NGC 6951, NGC 7479)...

    The origin of the ionization of the diffuse ionized gas in spirals. II. Modelling the distribution of ionizing radiation in NGC 157
    In this paper we make a quantitative study of the hypothesis that the diffuse Hα emitted from the discs of spiral galaxies owes its origin to the ionizing...

    The origin of the light distribution in spiral galaxies
    We analyse a high-resolution, fully cosmological, hydrodynamical disc galaxy simulation, to study the source of the double-exponential light profiles seen in...

    The origin of the LMC stellar bar: clues from the SFH of the bar and inner disc
    We discuss the origin of the Large Magellanic Cloud (LMC) stellar bar by comparing the star formation histories (SFHs) obtained from deep colour-magnitude...
  • Publication
    The origin of the mid-infrared nuclear polarization of active galactic nuclei
    We combine new (NGC 1275, NGC 4151, and NGC 5506) and previously published (Cygnus A, Mrk 231, and NGC 1068) sub-arcsecond resolution mid-infrared (MIR; 8-13 μm...
  • Publication
    The origin of the planetary nebula M 1-16. A morpho-kinematic and chemical analysis
    We investigated the origin of the Planetary Nebula (PN) M 1-16 using narrow-band optical imaging, and high- and low-resolution optical spectra to perform a...

    The Origin of the Relation between Metallicity and Size in Star-forming Galaxies
    For the same stellar mass, physically smaller star-forming galaxies are also metal richer. What causes the relation remains unclear. The central star-forming...

    The origin of the reversed granulation in the solar photosphere
    Aims:We study the structure and reveal the physical nature of the reversed granulation pattern in the solar photosphere by means of 3-dimensional radiative...
