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)...
Dusty Supernovae Running the Thermodynamics of the Matter Reinserted within Young and Massive Super Stellar Clusters
Following the observational and theoretical evidence that points at core-collapse supernovae (SNe) as major producers of dust, here we calculate the...
DW Cancri: a magnetic VY Scl star with an orbital period of 86 min
We present the first time-resolved spectroscopic study of the cataclysmic variable DW Cancri. We have determined an orbital period of 86.10 +/- 0.05 min, which...
Dwarf galaxies in the Coma cluster - I. Velocity dispersion measurements
We present the study of a large sample of early-type dwarf galaxies in the Coma cluster observed with DEIMOS on the Keck II to determine their internal velocity...
Dwarf Galaxies with Central Cores in Modified Newtonian Dynamics Gravity
Some dwarf galaxies are within the Mondian regime at all radii, i.e., the gravitational acceleration provided by the observed baryons is always below the...
