Ca II Triplet Spectroscopy of Small Magellanic Cloud Red Giants. V. Abundances and Velocities for 12 Massive Clusters
M. C. Parisi, L. V. Gramajo, D. Geisler +4
We aim to analyze the chemical evolution of the Small Magellanic Cloud adding 12 additional clusters to our existing sample having accurate and homogeneously derived metallicities.…
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…
An Intriguing Globular Cluster in the Galactic Bulge from the VVV Survey
D. Minniti, T. Palma, D. Camargo +7
Recent near-IR Surveys have discovered a number of new bulge globular cluster (GC) candidates that need to be further investigated. Our main objective is to use public data from th…
Discovery of new globular clusters in the Sagittarius dwarf galaxy
D. Minniti, V. Ripepi, J. G. Fernández-Trincado +14
Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way (MW). In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important prob…
VVVX-Gaia Discovery of a Low Luminosity Globular Cluster in the Milky Way Disk
E. R. Garro, D. Minniti, M. Gómez +20
Milky Way globular clusters (MW GCs) are difficult to identify at low Galactic latitudes because of high differential extinction and heavy star crowding. The new deep near-IR image…
CCD Washington photometry of 10 open clusters or candidates projected close to the Galactic plane
Juan J. Clariá, M. Celeste Parisi, Tali Palma +2
We present high-quality CCD photometry in the Washington system C and T1 passbands down to T1 ~ 19.5 mag in the fields of 10 Galactic open clusters (OCs) or candidates projected cl…
FSR 1716: A new Milky Way Globular Cluster confirmed using VVV RR Lyrae stars
Dante Minniti, Tali Palma, Istvan Dékány +35
We use deep multi-epoch near-IR images of the VISTA Variables in the Vía Láctea (VVV) Survey to search for RR Lyrae stars towards the Southern Galactic plane. Here we report the di…
New variable stars discovered in the fields of three Galactic open clusters using the VVV Survey
Tali Palma, Dante Minniti, Istvan Dékány +5
This project is a massive near-infrared (NIR) search for variable stars in highly reddened and obscured open cluster (OC) fields projected on regions of the Galactic bulge and disk…
Determination of reddening and age for ten Large Magellanic Cloud star clusters from integrated spectroscopy
Andrea V. Ahumada, Luis R. Vega, Juan J. Clariá +2
We present flux-calibrated integrated spectra in the optical range (3700-6800 Å) obtained at Complejo Astronómico El Leoncito (CASLEO, Argentina) for a sample of 10 concentrated st…
A catalogue of Large Magellanic Cloud star clusters observed in the Washington photometric system
Tali Palma, Luciana V. Gramajo, Juan J. Clariá +3
The main goal of this study is to compile a catalogue including the fundamental parameters of a complete sample of 277 star clusters (SCs) of the Large Magellanic Cloud (LMC) obser…
Probing the Large Magellanic Cloud's recent chemical enrichment history through its star clusters
Tali Palma, Juan J. Clariá, Doug Geisler +2
We present Washington system colour-magnitude diagrams (CMDs) for 17 practically unstudied star clusters located in the bar as well as in the inner disc and outer regions of the La…
VISTA Variables in the Vía Láctea (VVV): Halfway Status and Results
Maren Hempel, Dante Minniti, István Dékány +89
The VISTA Variables in the Vía Láctea (VVV) survey is one of six public ESO surveys, and is now in its 4th year of observing. Although far from being complete, the VVV survey has a…
CCD Washington photometry of four poorly studied open clusters in the two inner quadrants of the galactic plane
N. Marcionni, J. J. Claria, M. C. Parisi +3
Complementing our Washington photometric studies on Galactic open clusters (OCs), we now focus on four poorly studied OCs located in the first and fourth Galactic quadrants, namely…
Age Determination of Fifteen Old to Intermediate-Age Small Magellanic Cloud Star Clusters
M. C. Parisi, D. Geisler, G. Carraro +6
We present CMDs in the V and I bands for fifteen star clusters in the Small Magellanic Cloud (SMC) based on data taken with the Very Large Telescope (VLT, Chile). We selected these…
A sample of relatively unstudied star clusters in the Large Magellanic Cloud: fundamental parameters determined from Washington photometry
Tali Palma, Juan J. Clariá, Doug Geisler +2
To enlarge our growing sample of well-studied star clusters in the Large Magellanic Cloud (LMC), we present CCD Washington CT1 photometry to T1 ~ 23 in the fields of twenty-three m…
Fast Integrated Spectra Analyzer: A New Computational Tool For Age and Reddening Determination of Small Angular Diameter Open Clusters
Alejandro Benítez-Llambay, Juan J. Clariá, Andrés E. Piatti
We present a new algorithm called 'Fast Integrated Spectra Analyzer" (FISA) that permits fast and reasonably accurate age and reddening determinations for small angular diameter op…
Ages and Metallicities of Star Clusters and Surrounding Fields in the Outer Disk of the Large Magellanic Cloud
