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…
The VVV Open Cluster Project II. Near-infrared sequences of 37 open clusters on eight-dimensional parameter space
K. Peña Ramírez, L. C. Smith, S. Ramírez Alegría +4
Open clusters are key coeval structures that help us understand star formation, stellar evolution and trace the physical properties of our Galaxy. In the past years, the isolation…
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…
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…
Probing the Dragonfish star-forming complex: the ionizing population of the young massive cluster Mercer 30
D. de la Fuente, F. Najarro, J. Borissova +11
The Dragonfish Nebula has been recently claimed to be powered by a superluminous but elusive OB association. Instead, systematic searches in near-infrared photometric surveys have…
Massive open star clusters using the VVV survey V. Young clusters with an OB stellar population
S. Ramírez Alegría, J. Borissova, A. -N. Chené +6
The ESO public survey VISTA Variables in the Vía Láctea (VVV) has contributed with deep multi-epoch photometry of the Galactic bulge and the adjacent part of the disk over 526 squa…
Massive open star clusters using the VVV survey IV. WR 62-2, a new very massive star in the core of the VVV CL041 cluster
A. -N. Chené, S. Ramírez Alegría, J. Borissova +8
Context The ESO Public Survey VISTA Variables in the Vía Láctea (VVV) provides deep multi-epoch infrared observations for an unprecedented 562 sq. degrees of the Galactic bulge and…
A not so massive cluster hosting a very massive star
S. Ramírez Alegría, A. -N. Chené, J. Borissova +4
We present the first physical characterization of the young open cluster VVV CL041. We spectroscopically observed the cluster main-sequence stellar population and a very-massive st…
Masgomas-4: Physical characterization of a double-core obscured cluster with a massive and very young stellar population
S. Ramírez Alegría, A. Marín-Franch, A. Herrero
The discovery of new, obscured massive star clusters has changed our understanding of the Milky Way star-forming activity from a passive to a very active star-forming machine. The…
Massive open star clusters using the VVV survey III: A young massive cluster at the far edge of the Galactic bar
S. Ramírez Alegría, J. Borissova, A. N. Chené +14
Context: Young massive clusters are key to map the Milky Way's structure, and near-IR large area sky surveys have contributed strongly to the discovery of new obscured massive stel…
Discovery of a young and massive stellar cluster: Spectrophotometric near-infrared study of Masgomas-1
S. Ramírez Alegría, A. Marín-Franch, A. Herrero
Context: Recent near-infrared data have contributed to the discovery of new (obscured) massive stellar clusters and massive stellar populations in previously known clusters in our…
Near-infrared study of the stellar population of Sh2-152
S. Ramírez Alegría, A. Herrero, A. Marín-Franch +5
Context: The discovery of new massive star clusters and massive stellar populations in previously known clusters in our Galaxy by means of infrared studies has changed our view of…
Near-infrared spectroscopy in NGC 7538
E. Puga, A. Marín-Franch, F. Najarro +7
The characterisation of the stellar population toward young high-mass star-forming regions allows to constrain fundamental cluster properties like distance and age. These are essen…
