Previous numerical studies had apparently ruled out the possibility that flares in galaxy discs could give rise to the apparent breaks in their luminosity...

PublicaciónUBRI photometry of globular clusters in the Leo group galaxy NGC 3379
We present wide-area UBRI photometry for globular clusters around the Leo group galaxy NGC 3379. Globular cluster candidates are selected from their B-band...

PublicaciónUltra diffuse galaxies in the Hydra I cluster from the LEWISProject: Phase-Space distribution and globular cluster richness
Although ultra diffuse galaxies (UDGs) are found in large numbers in clusters of galaxies, the role of the cluster environment in shaping their low surface...

PublicaciónUltra-bright CO and [{\rm{C}}\,{\rm{I}}] Emission in a Lensed z = 2.04 Submillimeter Galaxy with Extreme Molecular Gas Properties
We report the very bright detection of cold molecular gas with the IRAM NOEMA interferometer of the strongly lensed source WISE J132934.18+224327.3 at z = 2.04...

PublicaciónUltra-deep imaging of nearby galaxy outskirts from the ground
We show how present-day 10 meter class telescopes can provide broadband imaging 1.5-2 mag deeper than most previous results within a reasonable amount of time (...

PublicaciónUltra-deep imaging of NGC 1052-DF2 and NGC 1052-DF4 to unravel their origins
A number of scenarios have been proposed to explain the low velocity dispersion (and hence possible absence of dark matter) of the low surface brightness...

PublicaciónUltra-deep Sub-kiloparsec View of nearby Massive Compact Galaxies
Using Gemini North telescope ultra-deep and high-resolution (sub-kiloparsec) K-band adaptive optics imaging of a sample of four nearby (z ~ 0.15) massive (~1011...

PublicaciónUltra-diffuse galaxies outside clusters: clues to their formation and evolution
We identify six ultra-diffuse galaxies (UDGs) outside clusters in three nearby isolated groups (0.014 < z < 0.026) using very deep imaging in three different...

PublicaciónUltra-red Galaxies Signpost Candidate Protoclusters at High Redshift
We present images obtained with LABOCA of a sample of 22 galaxies selected via their red Herschel SPIRE colors. We aim to see if these luminous, rare, and...
