Spectroscopic metallicities and first α-element abundances of RR Lyrae stars in Baade's Window
J. Olivares Carvajal, Á. Rojas-Arriagada, M. Zoccali +10
RR Lyrae stars in the bulge have been reported to be associated with the spheroidal, relatively metal-poor component. They offer a way to trace this component with precise distance…
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…
On the Use of Field RR Lyrae as Galactic Probes -- VIII. Early Formation of the Galactic Spheroid
G. Bono, V. F. Braga, M. Fabrizio +54
We introduce a new photometric catalog of RR Lyrae variables (RRLs, 300,000) mainly based on data available in public datasets. We also present the largest and most homogeneo…
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…
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…
Comparing bulge RR Lyrae stars with bulge giants -- Insight from 3D kinematics
J. Olivares Carvajal, M. Zoccali, M. De Leo +6
The structure and kinematics of the old component of the Galactic bulge are still a matter of debate. The bulk of the bulge as traced by red clump stars includes two main component…
Observed kinematics of the Milky Way nuclear stellar disk region
M. Zoccali, A. Rojas-Arriagada, E. Valenti +3
The nuclear region of the Milky Way is believed to host a nuclear stellar disk, co-spatial with the gaseous central molecular zone. Previous kinematical studies detected faster rot…
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 GIRAFFE Inner Bulge Survey (GIBS) III. Metallicity distributions and kinematics of 26 Galactic bulge fields
M. Zoccali, S. Vasquez, O. A. Gonzalez +9
Several recent studies have demonstrated that the Galactic bulge hosts two components with different mean metallicities, and possibly different spatial distribution and kinematics.…
