PublicationA 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...

PublicationA 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...

PublicationA 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...

PublicationA 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...

PublicationA 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...

PublicationA 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...

PublicationA diffuse tidal dwarf galaxy destined to fade out as a "dark galaxy"
We have explored the properties of a peculiar object detected in deep optical imaging and located at the tip of an H I tail emerging from Hickson Compact Group...

PublicationA distance of 13 Mpc resolves the claimed anomalies of the galaxy lacking dark matter
The claimed detection of a diffuse galaxy lacking dark matter represents a possible challenge to our understanding of the properties of these galaxies and...
