    A deep learning approach to test the small-scale galaxy morphology and its relationship with star formation activity in hydrodynamical simulations
    Hydrodynamical simulations of galaxy formation and evolution attempt to fully model the physics that shapes galaxies. The agreement between the morphology of...

    A deep look at the nuclear region of UGC 5101 through high angular resolution mid-IR data with GTC/CanariCam
    We present an analysis of the nuclear infrared (IR, 1.6-18 μm) emission of the ultraluminous IR galaxy UGC 5101 to derive the properties of its active galactic...

    A deep narrowband survey for planetary nebulae at the outskirts of M 33
    Context. Planetary nebulae (PNe) are excellent tracers of stellar populations with low surface brightness, and therefore provide a powerful method to detect and...

    A deep search for the host galaxies of gamma-ray bursts with no detected optical afterglow
    Context. Gamma-ray bursts (GRBs) can provide information about star formation at high redshifts. Even in the absence of a bright optical/near-infrared/radio...

    A Deep View of the Monoceros Ring in the Anticenter Direction: Clues of Its Extra-galactic Origin
    We present the results of deep imaging obtained at the Canada-France-Hawaii Telescope with MegaCam in the anticenter direction at two different heights above...

    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 detailed look at chemical abundances in the Magellanic Clouds
    We determine elemental abundances of He, N, O, Ne, S, and Ar in Magellanic Cloud planetary nebulae (PNe) using direct methods and a large set of observed ions...

    A detailed look at the stellar populations in green valley galaxies
    The green valley (GV) represents an important transitional state from actively star-forming galaxies to passively evolving systems. Its traditional definition...

    A detailed two-dimensional stellar population study of M32
    We present integral field spectroscopy of the 9×12arcsec2 circumnuclear region of M32 obtained with the 2D_FIS fibre optics spectrographs installed at the 4.2-m...
