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…

Infrared photometry and CaT spectroscopy of the most metal-poor in-situ globular cluster VVV-CL001

W. Haro Moya, C. Moni Bidin, M. C. Parisi +11

Globular clusters in the Galactic bulge are difficult to study due to high extinction and severe crowding. VVV-CL001 is an old, metal-poor, and fast cluster in the inner bulge, who…

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…

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 JWST Galactic Center Survey -- A White Paper

Rainer Schoedel, Steve Longmore, Jonny Henshaw +111

The inner hundred parsecs of the Milky Way hosts the nearest supermassive black hole, largest reservoir of dense gas, greatest stellar density, hundreds of massive main and post ma…

Using classical Cepheids to study the far side of the Milky Way disk. II. The spiral structure in the first and fourth Galactic quadrants

J. H. Minniti, M. Zoccali, A. Rojas-Arriagada +9

In an effort to improve our understanding of the spiral arm structure of the Milky Way, we use Classical Cepheids (CCs) to increase the number of young tracers on the far side of t…

MOONS Surveys of the Milky Way and its Satellites

O. A. Gonzalez, A. Mucciarelli, L. Origlia +37

The study of resolved stellar populations in the Milky Way and other Local Group galaxies can provide us with a fossil record of their chemo-dynamical and star-formation histories…
