PublicaciónUBVRI photometry of stars in Berkeley 86 (Deeg+, 1996)
Based on photometry of deep CCD frames of the central region of the OB cluster Berkeley 86, we derive the cluster mass function. The absence of current star...

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-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...
