    DENIS: A Deep Near-Infrared Survey of the southern sky
    The Deep Near-Infrared Survey (DENIS) project is the first attempt to carry out a complete digitized survey of the southern sky in the range 1-2.5 micrometers...

    Density Bounded H II Regions: Ionization of the Diffuse Interstellar and Intergalactic Media
    We present a study of the diffuse ionized gas (DIG) for a sample of nearby spiral galaxies using Hα images, after constructing their H II region catalogues. The...

    Density Bounding in the H II Regions of Galactic Disks: Evidence and Consequences
    We present four lines of evidence leading to the conclusion that a notable fraction of the ionizing photon emission from the stars within H II regions in the...

    Density bounding in the HII regions of galactic discs: evidence and consequences
    We present four lines of evidence leading to the conclusion that the HII regions in the discs of normal galaxies,notably the highly luminous regions,are density...

    Density profiles of galaxy bulges and nuclei
    The bulge contribution to the inner density profile of a galaxy is well traced by the bulge's NIR surface brightness profile. We map the surface brightness...

    Density studies of giant extragalactic H II regions
    The variation of the electron density with position in a selected group of bright giant extragalactic H II regions has been studied using long slit...

    Density wave triggered star formation in grand design spirals
    In normal spiral galaxies the arms are the main sites for star formation. This is the cause of their optical contrast compared with the rest of the disc. The...
