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 production and coma morphology of 67P/Churyumov-Gerasimenko during the 2002-2003 apparition
Light curves and images of 67P/Churyumov-Gerasimenko are presented for the 2002-2003 apparition based on amateur CCD monitoring using a standardised method to...
Dust production and coma morphology of 67P/Churyumov-Gerasimenko during the 2002/2003 apparition. II. A comparative study of dust production in 46P/Wirtanen and 67P/Churyumov-Gerasimenko during their 2002/2003 apparition
A comparison is made of the light curves and and dust production of the initial target for the ROSETTA mission, 46P/Wirtanen and the new target 67P/Churyumov...
Dust properties of double-tailed active asteroid (6478) Gault
Context. Asteroid (6478) Gault was discovered to exhibit a comet-like tail in observations from December 2018, becoming a new member of the so-called active...
Context. Since the mid-1990s, the sample of Lyman-break galaxies (LBGs) has been growing thanks to the increasing sensitivities in the optical and in near...
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...
Dust scattering and kinematics within the envelope of IRAS 09371+1212.
We have acquired narrow and broad band imaging, together with high and low resolution spectroscopy for the source IRAS 09371+1212. As a result, we are able to...
Dust-obscured star formation in the outskirts of XMMU J2235.3-2557, a massive galaxy cluster at z = 1.4
Star formation (SF) in the galaxy populations of local massive clusters is reduced with respect to field galaxies, and tends to be suppressed in the core region...
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)...
