    A measurement of galaxy halo mass from the surrounding H I Lyα absorption
    We measure the dark matter halo masses of ≈ 2.36 UV colour-selected star-forming galaxies by matching the observed median H I Lyα absorption around them, as...

    A mid-infrared spectroscopic atlas of local active galactic nuclei on sub-arcsecond resolution using GTC/CanariCam
    We present an atlas of mid-infrared (mid-IR) ˜ 7.5-13 μm spectra of 45 local active galactic nuclei (AGN) obtained with CanariCam on the 10.4 m Gran Telescopio...

    A mid-infrared statistical investigation of clumpy torus model predictions
    We present new calculations of the Clumpy AGN Tori in a 3D geometry (CAT3D) clumpy torus models, which now include a more physical dust sublimation model as...

    A mid-infrared view of the inner parsecs of the Seyfert galaxy Mrk 1066 using CanariCam/GTC
    We present mid-infrared (MIR) imaging and spectroscopic data of the Seyfert 2 galaxy Mrk 1066 obtained with CanariCam (CC) on the 10.4-m Gran Telescopio...

    A minor merger origin for stellar inner discs and rings in spiral galaxies
    Context. Observations have shown that inner discs and rings (IDs and IRs) are not preferably found in barred galaxies, which indicates that their formation may...

    A Minor-Merger Origin for Inner Disks and Rings in Early-Type Galaxies
    Nuclear disks and rings are frequent galaxy substructures, for a wide range of morphological types [from S0 to Sc, see e.g., 1, 2]. We have investigated the...

    A molecular gas-rich GRB host galaxy at the peak of cosmic star formation
    We report the detection of the CO(3-2) emission line from the host galaxy of gamma-ray burst (GRB) 080207 at z = 2.086. This is the first detection of molecular...

    A Morphological and Statistical Analysis of Ansae in Barred Galaxies
    Many barred galaxies show a set of symmetric enhancements at the ends of the stellar bar, called ansae, or the "handles" of the bar. Ansa bars have been in the...

    A morphological study of galaxies in ZwCl0024+1652, a galaxy cluster at redshift z ˜ 0.4
    The well-known cluster of galaxies ZwCl0024+1652 at z ˜ 0.4 lacks an in-depth morphological classification of its central region. While previous studies provide...
