The deepest color-magnitude diagrams for the benchmark open cluster NGC 2437 from Gaia and VVVX
Tali Palma, Matías Gómez, Dante Minniti +8
Deep photometry of Galactic star clusters provides one of the most powerful tools for determining their physical properties. In particular, in low Galactic latitude regions that su…
A near-infrared stellar atlas of the Galactic plane from the VVVX survey
Javier Alonso-García, Maren Hempel, Roberto K. Saito +12
The VISTA Variables in the Via Lactea eXtended (VVVX) ESO public survey observed the Galactic plane and the outer Galactic bulge in the near-infrared to mitigate the effects of ext…
Revealing the Origins of Galactic Globular Clusters via Their Mg-Al Abundances
Shihui Lin, Baitian Tang, Genghao Liu +4
Many Galactic globular clusters (GCs) originated in diverse host galaxies before being subsequently incorporated into the Milky Way through hierarchical galaxy assembly. Identifyin…
Variable stars in the VVV globular clusters III. RR Lyrae stars in the inner Galactic globular clusters
Javier Alonso-García, Leigh C. Smith, Jason L. Sanders +13
High reddening near the Galactic plane hampers observations and proper characterization of the globular clusters (GCs) located toward the inner regions of the Milky Way. The VISTA…
VIRAC2: NIR Astrometry and Time Series Photometry for 500M+ Stars from the VVV and VVVX Surveys
Leigh C. Smith, Philip W. Lucas, Sergey E. Koposov +11
We present VIRAC2, a catalogue of positions, proper motions, parallaxes and , , , , and near-infrared photometric time series of 545 346 537 unique stars. The cat…
Signature of systemic rotation in 21 Galactic Globular Clusters from APOGEE-2
Ilaria Petralia, Dante Minniti, José G. Fernández-Trincado +2
Context. Traditionally, Globular Clusters (GCs) have been assumed to be quasi-relaxed non-rotating systems, characterized by spherical symmetry and orbital isotropy. However, in re…
High-precision astrometry with VVV -- II. A near-infrared extension of Gaia into the Galactic plane
M. Griggio, M. Libralato, A. Bellini +4
Aims. We use near-infrared, ground-based data from the VISTA Variables in the Via Lactea (VVV) survey to indirectly extend the astrometry provided by the Gaia catalog to objects in…
The globular cluster VVV CL002 falling down to the hazardous Galactic centre
D. Minniti, N. Matsunaga, J. G. Fernandez-Trincado +15
Context. The Galactic centre is hazardous for stellar clusters because of the strong tidal force. Supposedly, many clusters were destroyed and contributed stars to the crowded stel…
The epoch of the Milky Way's bar formation: dynamical modelling of Mira variables in the nuclear stellar disc
Jason L. Sanders, Daisuke Kawata, Noriyuki Matsunaga +4
A key event in the history of the Milky Way is the formation of the bar. This event affects the subsequent structural and dynamical evolution of the entire Galaxy. When the bar for…
