Revisited parameters for the twin bulge globular clusters NGC 6528 and NGC 6553
S. Ortolani, S. O. Souza, D. Nardiello +2
NGC 6528 and NGC 6553 are among the most metal-rich globular clusters in the Galactic bulge. They represent the upper end of the chemical enrichment in the Galaxy, and can inform o…
Combined Gemini-South and HST photometric analysis of the globular cluster NGC 6558. The age of the metal-poor population of the Galactic Bulge
S. O. Souza, M. Libralato, D. Nardiello +8
NGC~6558 is a low-galactic latitude globular cluster projected in the direction of the Galactic bulge. Due to high reddening, this region presents challenges in deriving accurate p…
The VISTA Variables in the Vía Láctea eXtended (VVVX) ESO public survey: Completion of the observations and legacy
R. K. Saito, M. Hempel, J. Alonso-García +143
The ESO public survey VISTA Variables in the Vía Láctea (VVV) surveyed the inner Galactic bulge and the adjacent southern Galactic disk from . Upon its conclusion, the c…
A census of new globular clusters in the Galactic bulge
E. Bica, S. Ortolani, B. Barbuy +1
The number of known globular clusters in the Galactic bulge has been increasing steadily thanks to different new surveys. The aim of this study is to provide a census of the newly…
The VISCACHA survey -- VII. Assembly history of the Magellanic Bridge and SMC Wing from star clusters
R. A. P. Oliveira, F. F. S. Maia, B. Barbuy +15
The formation scenario of the Magellanic Bridge during an encounter between the Large and Small Magellanic Clouds Myr ago, as proposed by -body models, would be impri…
The VISCACHA survey -- V. Rejuvenating three faint SMC clusters
E. Bica, F. F. S. Maia, R. A. P. Oliveira +9
We present the analysis of three faint clusters of the Small Magellanic Cloud RZ82, HW42 and RZ158. We employed the SOAR telescope instrument SAM with adaptive optics, allowing us…
