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 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…
The VISCACHA survey -- IV. The SMC West Halo in 8D
B. Dias, M. C. Parisi, M. Angelo +18
The structure of the Small Magellanic Cloud (SMC) is very complex, in particular in the periphery that suffers more from the interactions with the Large Magellanic Cloud (LMC). A w…
Precise distances from OGLE-IV member RR Lyrae stars in six bulge globular clusters
R. A. P. Oliveira, S. Ortolani, B. Barbuy +6
Context. RR Lyrae stars are useful standard candles allowing one to derive accurate distances for old star clusters. Based on the recent catalogues from OGLE-IV and Gaia Early Data…
FSR 1776: a new globular cluster in the Galactic bulge?
B. Dias, T. Palma, D. Minniti +6
(ABRIDGED) Recent near-IR surveys have uncovered a plethora of new globular cluster (GC) candidates towards the Milky Way bulge. These new candidates need to be confirmed as real G…
