LSST Cadence Optimization White Paper: The Definitive Map of the Galactic bulge
Oscar A. Gonzalez, Will Clarkson, Victor P. Debattista +14
We recommend configuring the LSST coverage of the inner Galactic plane to allow the production of the definitive age/metallicity map of the Galactic bulge from LSST data, matched t…
unVEil the darknesS of The gAlactic buLgE (VESTALE)
G. Bono, M. Dall'Ora, M. Fabrizio +55
The main aim of this experiment is to provide a complete census of old (t > 10 Gyr, RR Lyrae, type II Cepheids, red horizontal branch), intermediate age (red clump, Miras) and youn…
The structure behind the Galactic bar traced by red clump stars in the VVV survey
Oscar A. Gonzalez, Dante Minniti, Elena Valenti +8
Red clump stars are commonly used to map the reddening and morphology of the inner regions of the Milky Way. We use the new photometric catalogues of the VISTA Variables in the Vía…
Milky Way demographics with the VVV survey. IV. PSF photometry from almost one billion stars in the Galactic bulge and adjacent southern disk
Javier Alonso-García, Roberto K. Saito, Maren Hempel +10
The inner regions of the Galaxy are severely affected by extinction, which limits our capability to study the stellar populations present there. The Vista Variables in the Via Lact…
Weighing the two stellar components of the Galactic Bulge
M. Zoccali, E. Valenti, O. A. Gonzalez
Recent spectroscopic surveys of the Galactic bulge have unambiguously shown that the bulge contains two main components, that are best separated in their iron content, but also dif…
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.…
