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…
From the inner Milky Way to Local Volume galaxies: resolved stellar populations with ELT-HARMONI
Oscar A. Gonzalez, Giuseppina Battaglia
We discuss the predicted performance of the HARMONI spectrograph and the ELT in the context of two specific science cases: resolved stellar populations of Local Volume galaxies and…
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…
