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…
Unveiling the structural content of NGC 6357 via kinematics and NIR variability
C. Ordenes-Huanca, M. Zoccali, A. Bayo +3
NGC 6357, a star-forming complex at kpc from the Sun, contains giant molecular clouds and three prominent star clusters alongside with HII regions, very massive stars an…
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…
New type II Cepheids from VVV data towards the Galactic center
V. F. Braga, R. Contreras Ramos, D. Minniti +5
The Galactic center (GC) is the densest region of the Milky Way. Variability surveys towards the GC potentially provide the largest number of variable stars per square degree withi…
New Near-Infrared light-curve templates for RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +34
We provide homogeneous optical (UBVRI) and near-infrared (JHK) time series photometry for 254 cluster (omega Cen, M4) and field RR Lyrae (RRL) variables. We ended up with more than…
Ultra Long Period Cepheids: a primary standard candle out to the Hubble flow
G. Fiorentino, G. Clementini, M. Marconi +7
The cosmological distance ladder crucially depends on classical Cepheids (with P=3-80 days), which are primary distance indicators up to 33 Mpc. Within this volume, very few SNe Ia…
The Unimodal Distribution Of Blue Straggler Stars in M75 (NGC 6864)
R. Contreras Ramos, F. R. Ferraro, E. Dalessandro +2
We have used a combination of multiband high-resolution and wide-field ground-based observations to image the Galactic globular cluster M75 (NGC 6864). The extensive photometric sa…
Spatial distribution and evolution of the stellar populations and candidate star clusters in the Blue Compact Dwarf I Zwicky 18
R. Contreras Ramos, F. Annibali, G. Fiorentino +7
The evolutionary properties and spatial distribution of I Zwicky 18 stellar populations are analyzed by means of HST/ACS deep and accurate photometry. The comparison of the resulti…
Pulsation Models for Ultra-Low (Z=0.0004) Metallicity Classical Cepheids
M. Marconi, I. Musella, G. Fiorentino +7
Classical Cepheids are primary distance indicators playing a fundamental role in the calibration of the extragalactic distance scale. The possible dependence of their characteristi…
