Comparing the properties of the X-shaped bulges of NGC 4710 and the Milky Way with MUSE
(EDP SCIENCES, 2016-06)
Context. Our view of the structure of the Milky Way and, in particular, its bulge is obscured by the intervening stars, dust, and gas in the disc. While great progress in understanding the bulge has been achieved with past ...

Gauging the Helium Abundance of the Galactic Bulge RR Lyrae Stars
(Institute of Physics Publishing, 2018)
We report the first estimate of the He abundance of the population of RR Lyrae stars in the Galactic bulge. This is done by comparing the recent observational data with the latest models. We use the large samples of ab-type ...
MACHO RR LYRAE IN THE INNER HALO AND BULGE
(AMERICAN CONCRETE INSTITUTE, 1999)
The RR Lyrae in the bulge have been proposed to be the oldest
populations in the Milky Way, tracers of how the galaxy formed. We study
here the distribution of ~1600 bulge RR Lyrae stars found by the MACHO
Project. The RR ...
Mapping the stellar age of the Milky Way bulge with the VVV I. The method
(2019)
Context. Recent observational programs are providing a global view of the Milky Way bulge that serves as a template for detailed comparison with models and extragalactic bulges. A number of surveys (VVV, GIBS, GES, ARGOS, ...

The WFC3 Galactic Bulge Treasury Program: Relative Ages of Bulge Stars of High and Low Metallicity
(Institute of Physics Publishing, 2018-08)
The Hubble Space Telescope/WFC3 multiband photometry spanning from the UV to the near-IR of four fields in the Galactic bulge, together with that for six template globular and open clusters, are used to photometrically tag ...
Heavy elements Ba, La, Ce, Nd, and Eu in 56 Galactic bulge red giants
(EDP SCIENCES, 2016-02)
Aims. The aim of this work is the study of abundances of the heavy elements Ba, La, Ce, Nd, and Eu in 56 bulge giants (red giant branch and red clump) with metallicities ranging from 1 : 3 dex to 0 : 5 dex.
Methods. ...
