New VVV Survey Globular Cluster Candidates in the Milky Way Bulge
(Institute of Physics Publishing, 2017-11)
It is likely that a number of Galactic globular clusters remain to be discovered, especially toward the Galactic bulge. High stellar density combined with high and differential interstellar reddening are the two major ...
Proper motions in the VVV Survey: Results for more than 15 million stars across NGC 6544
(EDP Sciences, 2017)
Context. In the last six years, the VISTA Variable in the Vía Láctea (VVV) survey mapped 562 sq. deg. across the bulge and southern disk of the Galaxy. However, a detailed study of these regions, which includes ∼36 globular ...
THE GAIA-ESO SURVEY: METAL-RICH BANANAS IN THE BULGE
(IOP PUBLISHING, 2016-06)
We analyze the kinematics of similar to 2000 giant stars in the direction of the Galactic bulge, extracted from the Gaia-ESO survey in the region -10 degrees less than or similar to l less than or similar to 10 degrees and ...
Chemically Dissected Rotation Curves of the Galactic Bulge from Main-sequence Proper Motions
(Institute of Physics Publishing, 2018-05)
We report results from an exploratory study implementing a new probe of Galactic evolution using archival Hubble Space Telescope imaging observations. Precise proper motions are combined with photometric relative metallicity ...
Oxygen and zinc abundances in 417 Galactic bulge red giants
(EDP Sciences, 2018)
Context. Oxygen and zinc in the Galactic bulge are key elements for the understanding of the bulge chemical evolution. Oxygen-to-iron abundance ratios provide a most robust indicator of the star formation rate and chemical ...
