    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 around R Coronae Borealis Stars. I. Spitzer/Infrared Spectrograph Observations
    Spitzer/infrared spectrograph (IRS) spectra from 5 to 37 μm for a complete sample of 31 R Coronae Borealis stars (RCBs) are presented. These spectra are...

    Dust Around R Coronae Borealis Stars. II. Infrared Emission Features in an H-poor Environment
    Residual Spitzer/Infrared Spectrograph spectra for a sample of 31 R Coronae Borealis (RCB) stars are presented and discussed in terms of narrow emission...

    Dust Environment Model of the Interstellar Comet 2I/Borisov
    2I/Borisov is the first interstellar comet discovered on 2019 August 30, and it soon showed a coma and a dust tail. This study reports the results of images...

    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 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...

    Dust Loss from Activated Asteroid P/2015 X6
    We present observations and dust tail models of activated asteroid P/2015 X6 from deep imaging data acquired at the 10.4 m Gran Telescopio Canarias (GTC) from...

    Dust Reverberation Mapping in Distant Quasars from Optical and Mid-infrared Imaging Surveys
    The size of the dust torus in active galactic nuclei (AGNs) and their high-luminosity counterparts, quasars, can be inferred from the time delay between UV...

    Dusty Starbursts Masquerading as Ultra-high Redshift Galaxies in JWST CEERS Observations
    Lyman-break galaxy (LBG) candidates at z ≳ 10 are rapidly being identified in James Webb Space Telescope (JWST)/NIRCam observations. Due to the (redshifted)...
