A two-stage settling of the Milky Way disk revealed by precise ChronoGal ages
David Mirabal, Carme Gallart, Tomás Ruiz-Lara +9
The spatial distribution of Galactic disk stars of different ages and metallicities encodes its dynamical evolution history and formation pathways. The lack of precise ages for lar…
Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal): IV. On the inner Milky Way stellar age distribution
Tomás Ruiz-Lara, David Mirabal, Carme Gallart +15
The Milky Way's inner region is dominated by a stellar bar and a boxy-peanut shaped bulge. However, which stellar populations inhabit the inner Galaxy or how star formation proceed…
New kinematic map of the Milky Way bulge
Carlos Quezada, Manuela Zoccali, Elena Valenti +7
The kinematics of the Milky Way bulge is known to be complex, reflecting the presence of multiple stellar components with distinct chemical and spatial properties. In particular, t…
Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) II. Unveiling the formation and evolution of the kinematically selected Thick and Thin Discs
Emma Fernández-Alvar, Tomás Ruiz-Lara, Carme Gallart +16
Understanding the formation and evolution of the Milky Way's thin and thick discs is crucial to galaxy formation studies. We derive age and metallicity distributions of the kinemat…
Chronology of our Galaxy from Gaia CMD-fitting (ChronoGal): the early formation of the Milky Way disk and the impact of Gaia-Sausage-Enceladus
C. Gallart, E. Fernández-Alvar, S. Cassisi +7
The derivation of precise stellar ages is considered the current major challenge to reconstruct the chronology of the Milky Way. Color-magnitude diagram (CMD)-fitting offers a robu…
Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal) -- III. Age and metallicity distribution of Gaia-Sausage-Enceladus stars near the Sun
Yllari K. González-Koda, Tomás Ruiz-Lara, Carme Gallart +14
Context. Gaia-Sausage-Enceladus is considered the last major merger that contributed to the formation of the Milky Way. Its remnants dominate the nearby accreted stellar halo of th…
Cluster Ages to Reconstruct the Milky Way Assembly (CARMA) I. The final word on the origin of NGC6388 and NGC6441
Davide Massari, Fernando Aguado-Agelet, Matteo Monelli +11
We present CARMA, the Cluster Ages to Reconstruct the Milky Way Assembly project, that aims at determining precise and accurate age measurements for the entire system of known Gala…
The diffuse interstellar band around 8620 Å II. Kinematics and distance of the DIB carrier
H. Zhao, M. Schultheis, A. Rojas-Arriagada +4
We aim to make use of the measurements from the Giraffe Inner Bulge Survey (GIBS) and the GaiaESO survey (GES) to study the kinematics and distance of the carrier of DIB862…
A new distance to the Brick, the dense molecular cloud G0.253+0.016
M. Zoccali, E. Valenti, F. Surot +3
We analyse the near infrared colour magnitude diagram of a field including the giant molecular cloud G0.253+0.016 (a.k.a. The Brick) observed at high spatial resolution, with HAWK-…
The diffuse interstellar band around 8620 Å I. Methods and application to the GIBS data set
H. Zhao, M. Schultheis, A. Recio-Blanco +6
We developed a set of procedures to automatically detect and measure the DIB around 8620 Å (the Gaia DIB) for a wide range of temperatures. The DIB profile is fit with a Gaussian f…
A hundred new eclipsing binary system candidates studied in a near-infrared window in the VVV survey
L. V. Gramajo, T. Palma, D. Minniti +4
We present the first results obtained from an extensive study of eclipsing binary (EB) system candidates recently detected in the VISTA Variables in the Vía Láctea (VVV) near-infra…
Mapping the stellar age of the Milky Way bulge with the VVV. III. High resolution reddening map
F. Surot, E. Valenti, O. A. Gonzalez +4
The detailed study of the Galactic bulge stellar population necessarily requires an accurate representation of the interstellar extinction particularly toward the Galactic plane an…
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…
VVV WIN 17333349: a low extinction window to probe the far side of the Milky Way bulge
Roberto K. Saito, Dante Minniti, Robert A. Benjamin +5
Windows of low extinction in the Milky Way (MW) have been used along the past decades for the study of the Galactic structure and the stellar population across the inner bulge and…
Mapping the stellar age of the Milky Way bulge with the VVV. II. Deep JKs catalogs release based on PSF photometry
F. Surot, E. Valenti, S. L. Hidalgo +6
The bulge represents the best compromise between old and massive Galactic component, and as such its study is a valuable opportunity to understand how the bulk of the Milky Way for…
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…
