    Double Bars, Inner Disks, and Nuclear Rings in Early-Type Disk Galaxies
    We present results from a survey of an unbiased sample of 38 early-type (S0-Sa), low-inclination, optically barred galaxies in the field, using images both from...

    Double-barred galaxies. I. A catalog of barred galaxies with stellar secondary bars and inner disks
    I present a catalog of 67 barred galaxies which contain distinct, elliptical stellar structures inside their bars. Fifty of these are double-barred galaxies: a...

    Dust and gas in star-forming galaxies at z 3. Extending galaxy uniformity to 11.5 billion years
    We present millimetre dust emission measurements of two Lyman-break galaxies at z 3 and construct for the first time fully sampled infrared spectral energy...

    Dust and Gas Obscuration in ELAIS Deep X-Ray Survey Reddened Quasars
    Hard X-ray surveys have uncovered a large population of heavily obscured AGNs. They also reveal a population of quasars with moderate obscuration at both...

    Dust distribution in HII regions in nearby galaxies from optical and IR studies .
    We report on our ongoing project "Statistical studies of HII regions in the nearby extragalaxies". In EWASS 2014 we presented the overview of our detailed study...

    Dust in active galactic nuclei. Mid-infrared T-ReCS/Gemini spectra using the new RedCan pipeline
    Context. The unified model of active galactic nuclei (AGN) claims that the properties of AGN depend on the viewing angle of the observer with respect to a...

    Dust in Clusters: Separating the Contribution of Galaxies and Intracluster Media
    We have analyzed a sample of 327 clusters of galaxies, spanning the range of 0.06–0.70 in redshift. Strong constraints on their mean intracluster emission of...

    Dust in the central parsecs of unobscured AGN: more challenges to the torus
    A parsec-scale dusty torus is thought to be the cause of active galactic nuclei (AGN) dichotomy in the 1/2 types, narrow/broad emission lines. In a previous...

    Dust in the Polar Region as a Major Contributor to the Infrared Emission of Active Galactic Nuclei
    Dust around active galactic nuclei (AGNs) is distributed over a wide range of spatial scales and can be observed in the infrared (IR). It is generally assumed...
