Extinction law and stellar mass in the Nuclear Bulge from kinematically-selected red clump stars
Á. Valenzuela Navarro, M. Zoccali, E. Valenti +10
The Nuclear Bulge of the Milky Way harbors stellar populations that provide crucial insights into galaxy formation processes and serve as a nearby analog for understanding bulge fo…
Globular clusters in \textsc{OrbIT}: complete dynamical characterisation of the globular cluster population of the Milky Way through updated orbital reconstruction
Michele De Leo, Manuela Zoccali, Julio Olivares-Carvajal +3
In hierarchical structure formation, the content of a galaxy is determined both by its in-situ processes and by material added via accretions. Globular clusters in particular repre…
Unveiling VVV/WISE Mira variables on the far side of the Galactic disk: Distances, kinematics and a new extinction law
Rogelio Albarracín, M. Zoccali, J. Olivares Carvajal +8
The structure and kinematics of the Milky Way disk are largely inferred from the solar vicinity. To gain a comprehensive understanding, it is essential to find reliable tracers in…
VVV catalog of ab-type RR Lyrae in the inner Galactic bulge
M. Zoccali, C. Quezada, R. Contreras Ramos +7
Context. Observational evidence has accumulated in the past years, showing that the Galactic bulge includes two populations, a metal poor and a metal rich one that, in addition to…
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 treasure behind the haystack: MUSE analysis of five recently discovered globular clusters
F. Gran, G. Kordopatis, M. Zoccali +10
After the second data release of Gaia, the number of new globular cluster candidates has increased importantly. However, most of them need to be properly characterised, both spectr…
The Pristine survey -- XXIII. Data Release 1 and an all-sky metallicity catalogue based on Gaia DR3 BP/RP spectro-photometry
Nicolas F. Martin, Else Starkenburg, Zhen Yuan +38
We used the spectro-photometric information of ~219 million stars from Gaia's DR3 to calculate synthetic, narrow-band, metallicity-sensitive CaHK magnitudes that mimic the observat…
Spectroscopic analysis of VVV CL001 cluster with MUSE
Julio Olivares Carvajal, Manuela Zoccali, Alvaro Rojas-Arriagada +4
Like most spiral galaxies, the Milky Way contains a population of blue, metal-poor globular clusters and another of red, metal-rich ones. Most of the latter belong to the bulge, an…
Hidden in the Haystack: Low-luminosity globular clusters towards the Milky Way bulge
F. Gran, M. Zoccali, I. Saviane +8
Recent wide-area surveys have enabled us to study the Milky Way with unprecedented detail. Its inner regions, hidden behind dust and gas, have been partially unveiled with the arri…
CAPOS: The bulge Cluster APOgee Survey I. Overview and initial ASPCAP results
Doug Geisler, Sandro Villanova, Julia E. O'Connell +39
Context. Bulge globular clusters (BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational d…
APOGEE view of the globular cluster NGC 6544
F. Gran, M. Zoccali, A. Rojas-Arriagada +16
The second phase of the APOGEE survey is providing near-infrared, high-resolution, high signal-to-noise spectra of stars in the halo, disk, bar and bulge of the Milky Way. The near…
How Many Components? Quantifying the Complexity of the Metallicity Distribution in the Milky Way Bulge with APOGEE
A. Rojas-Arriagada, G. Zasowski, M. Schultheis +14
We use data of 13,000 stars from the SDSS/APOGEE survey to study the shape of the bulge MDF within the region and , and spatially constr…
Globular cluster candidates in the Galactic bulge: Gaia and VVV view of the latest discoveries
F. Gran, M. Zoccali, R. Contreras Ramos +7
Thanks to the recent wide-area photometric surveys, the number of star cluster candidates have risen exponentially in the last few years. Most detections, however, are based only o…
The VVV Survey RR Lyrae Population in the Galactic Centre Region
Rodrigo Contreras Ramos, Dante Minniti, Felipe Gran +6
Deep near-IR images from the VVV Survey were used to search for RR Lyrae type ab (RRab) stars within 100' from the Galactic Centre (GC). A sample of 960 RRab stars were discovered.…
The Orbit of the new Milky Way Globular Cluster FSR1716 = VVV-GC05
Rodrigo Contreras Ramos, Dante Minniti, Jose G. Fernandez-Trincado +10
We use deep multi-epoch near-IR images of the VISTA Variables in the Via Lactea (VVV) Survey to measure proper motions (PMs) of stars in the Milky Way globular cluster FSR1716 = VV…
Proper motions in the VVV Survey: Results for more than 15 million stars across NGC 6544
R. Contreras Ramos, M. Zoccali, F. Rojas +8
Context: In the last six years, the VVV survey mapped 562 sq. deg. across the bulge and southern disk of the Galaxy. However, a detailed study of these regions, which includes $\si…

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…
Discovery of RR Lyrae Stars in the Nuclear Bulge of the Milky Way
D. Minniti, R. Contreras Ramos, M. Zoccali +4
Galactic nuclei, like the one of the Milky Way, are extreme places with high stellar densities and, in most cases, hosting a supermassive black hole. One of the scenarios proposed…
