Near-infrared spectroscopic observations of massive young stellar object candidates in the Central Molecular Zone
G. Nandakumar, M. Schultheis, A. Feldmeier-Krause +6
We present a spectroscopic follow-up of photometrically-selected young stellar object (YSO) candidates in the Central Molecular Zone of the Galactic center. Our goal is to quantify…
Effects of the selection function on metallicity trends in spectroscopic surveys of the Milky Way
G. Nandakumar, M. Schultheis, M. Hayden +3
We investigate here the effect of the selection function on the metallicity distribution function (MDF) and on the vertical metallicity gradient by studying similar lines of sight…
The Gaia-ESO Survey: Exploring the complex nature and origins of the Galactic bulge populations
A. Rojas-Arriagada, A. Recio-Blanco, P. de Laverny +36
Abridged: We used the fourth internal data release of the Gaia-ESO survey to characterize the bulge chemistry, spatial distribution, kinematics, and to compare it chemically with t…
The Gaia-ESO Survey: low-alpha element stars in the Galactic Bulge
A. Recio-Blanco, A. Rojas-Arriagada, P. de Laverny +17
We take advantage of the Gaia-ESO Survey iDR4 bulge data to search for abundance anomalies that could shed light on the composite nature of the Milky Way bulge. The alpha-elements…
Baade's window with APOGEE: Metallicities, ages and chemical abundances
M. Schultheis, A. Rojas-Arriagada, A. E. García Pérez +23
Baade's window (BW) is one of the most observed Galactic bulge fields in terms of chemical abundances. Due to its low and homogeneous interstellar absorption it is considered as a…
