    Do the Most Massive Black Holes at z = 2 Grow via Major Mergers?
    The most frequently proposed model for the origin of quasars holds that the high accretion rates seen in luminous active galactic nuclei (AGN) are primarily...

    Does equipartition hold in HFPs?
    Equipartition of energy between relativistic particles and magnetic field is known to be consistent with observations in most of the large size (hundreds of kpc...

    Does the virial mass drive the intra-cluster light?. Relationship between the ICL and M<SUB>vir</SUB> from VEGAS
    In this Letter, we revisit the relationship between the fraction of the intra-cluster light (ICL) as well as the virial mass and the fraction of early-type...

    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...
