    A 3D extinction map of the northern Galactic plane based on IPHAS photometry
    We present a 3D map of extinction in the northern Galactic plane derived using photometry from the INT/WFC Photometric Hα Survey of the northern Galactic plane...

    A conspicuous increase of Galactic contamination over CMBR anisotropies at large angular scales
    New calculations of the Galactic contamination over microwave background radiation anisotropies are carried out. On the one hand, when a frequency-dependent...

    A deeper look at the dust attenuation law of star-forming galaxies at high redshift
    A diverse range of dust attenuation laws is found in star-forming galaxies. In particular, Tress et al. (2018) studied the SHARDS survey to constrain the NUV...

    A galaxy-driven model of type Ia supernova luminosity variations
    Type Ia supernovae (SNe Ia) are used as standardizable candles to measure cosmological distances, but differences remain in their corrected luminosities which...

    A high-resolution study of near-IR diffuse interstellar bands, search for small-scale structure, time variability, and stellar features
    Context. The diffuse interstellar bands (DIBs) are a set of hundreds of unidentified absorption features that appear almost ubiquitously throughout the...

    A K-band central disc surface brightness correlation with scalelength for early-type disc galaxies, and the inclination correction
    The K-band light profiles from two statistically complete, diameter-limited samples of disc galaxies have been simultaneously modelled with a seeing-convolved...

    A logNHI = 22.6 Damped Lyα Absorber in a Dark Gamma-Ray Burst: The Environment of GRB 050401
    The optical afterglow spectrum of GRB 050401 (at z=2.8992+/-0.0004) shows the presence of a damped Lyα absorber (DLA), with logNHI=22.6+/-0.3. This is the...

    A mean redshift of 2.8 for Swift gamma-ray bursts
    The exceptionally high luminosities of gamma-ray bursts (GRBs), gradually emerging as extremely useful probes of star formation, make them promising tools for...

    A mid-infrared study of H II regions in the Magellanic Clouds: N88 A and N160 A
    Aims: To show the importance of high-spatial resolution observations of H II regions when compared with observations obtained with larger apertures such as ISO...
