Eridanus IV: an ultra-faint dwarf galaxy candidate discovered in the DECam local volume exploration survey
(IOP, 2021)
We present the discovery of a candidate ultra-faint Milky-Way satellite, Eridanus IV (DELVE J0505-0931), detected in photometric data from the DECam Local Volume Exploration survey (DELVE). Eridanus IV is a faint (M-V = - ...
The Brazil-Argentina gemini group for the study of globular cluster systems (BAGGs GCs): FLAMINGOS-2 and GMOS data for NGC 1395
(MDPI AG, 2017-08)
In this letter, we present preliminary results of the analysis of Flamingos-2 and GMOS-S photometry of the globular cluster (GC) system of the elliptical galaxy NGC1395. This is the first step of a long-term Brazilian-Argentinian ...
Slowly cooling white dwarfs in M13 from stable hydrogen burning
(Nature Research, 2021-11)
White dwarfs (WDs) are the final evolutionary product of the vast majority of stars in the Universe. They are electron-degenerate structures characterized by no stable thermonuclear activity, and their evolution is generally ...

Se presentan los resultados espectroscópicos Gemini-GMOS y fotometría infrarroja Flamingos-2 para los cúmulos globulares de NGC 1395 correspondientes a la colaboración BAGGS entre la Argentina y Brasil. La combinación con ...
Near-infrared observations of RR Lyrae and Type II Cepheid variables in the metal-rich bulge globular cluster NGC 6441
(2022)
Context. NGC 6441 is a bulge globular cluster (GC) with an unusual horizontal branch morphology and a rich population of RR Lyrae (RRL) and Type II Cepheid (T2C) variables that is unexpected for its relatively high ...
