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…
The GIRAFFE Inner Bulge Survey (GIBS) III. Metallicity distributions and kinematics of 26 Galactic bulge fields
M. Zoccali, S. Vasquez, O. A. Gonzalez +9
Several recent studies have demonstrated that the Galactic bulge hosts two components with different mean metallicities, and possibly different spatial distribution and kinematics.…
FORS2/VLT survey of Milky Way globular clusters II. Fe and Mg abundances of 51 Milky Way globular clusters on a homogeneous scale
Bruno Dias, Beatriz Barbuy, Ivo Saviane +5
(ABRIDGED) Globular clusters trace the formation and evolution of the Milky Way and surrounding galaxies, and outline their chemical enrichment history. To accomplish these tasks i…
High resolution spectroscopic analysis of seven giants in the bulge globular cluster NGC 6723
A. Rojas-Arriagada, M. Zoccali, S. Vásquez +5
Globular clusters associated with the Galactic bulge are important tracers of stellar populations in the inner Galaxy. High resolution analysis of stars in these clusters allows us…
The Giraffe Inner Bulge Survey (GIBS) II. Metallicity distributions and alpha element abundances at fixed Galactic latitude
O. A. Gonzalez, M. Zoccali, S. Vasquez +8
High resolution (R22,500) spectra for 400 red clump giants, in four fields within and $\rm -10^{\circ} \lesssim l \lesssim…
The Calcium Triplet metallicity calibration for galactic bulge stars
S. Vasquez, M. Zoccali, V. Hill +4
We present a new calibration of the Calcium II Triplet equivalent widths versus [Fe/H], constructed upon K giant stars in the Galactic bulge. This calibration will be used to deriv…
Chemical Abundances of the Highly Obscured Galactic Globular Clusters 2MASS GC02 and Mercer 5
Francisco Penaloza, Peter Pessev, Sergio Vasquez +3
We present the first high spectral resolution abundance analysis of two newly discovered Galactic globular clusters, namely Mercer 5 and 2MASS GC02 residing in regions of high inte…
FORS2/VLT survey of Milky Way globular clusters I. Description of the method for derivation of metal abundances in the optical and application to NGC 6528, NGC 6553, M 71, NGC 6558, NGC 6426 and Terzan 8
Bruno Dias, Beatriz Barbuy, Ivo Saviane +6
(abridged) We have observed almost 1/3 of the globular clusters in the Milky Way, targeting distant and/or highly reddened objects, besides a few reference clusters. A large sample…
The GIRAFFE Inner Bulge Survey (GIBS). I. Survey Description and a kinematical map of the Milky Way bulge
M. Zoccali, O. A. Gonzalez, S. Vasquez +10
The Galactic bulge is a massive, old component of the Milky Way. It is known to host a bar, and it has recently been demonstrated to have a pronounced boxy/peanut structure in its…
Deriving Metallicities from Calcium Triplet Spectroscopy in combination with Near Infrared Photometry
F. Mauro, C. Moni Bidin, D. Geisler +7
Context. [...] One of the most efficient methods is the measurement of the equivalent width (EW) of the Calcium II Triplet (CaT), corrected for the luminosity and temperature effec…
3D kinematics through the X-shaped Milky Way bulge
S. Vásquez, M. Zoccali, V. Hill +10
It has recently been discovered that the Galactic bulge is X-shaped, with the two southern arms of the X both crossing the lines of sight at l=0 and |b|>4, hence producing a double…
