CAPOS: The bulge Cluster APOgee Survey XII. Abundances for 98 PIGS metal-poor Bulge field giants

Carolina Salgado, Sandro Villanova, Doug Geisler +1

The inner Milky Way hosts overlapping stellar populations (bar--bulge, inner thin and thick disks, and halo), complicating population assignments along the line of sight. A joint c…

CAPOS: The bulge Cluster APOgee Survey XI. Unraveling the chemical composition of the bulge globular cluster NGC 6304

Carolina Montecinos, Doug Geisler, Cesar Muñoz +1

Context. With CAPOS, we can mitigate the observational difficulties limiting access to bulge globular clusters in the optical and investigate them in more detail in the near-IR. Ai…

CAPOS: The bulge Cluster APOGEE Survey VI. Characterizing multiple stellar populations and chemical abundances in the bulge globular cluster NGC 6569

Nicolás Barrera, Sandro Villanova, Doug Geisler +2

Context. The CAPOS project aims to obtain accurate mean abundances and radial velocities for many elements, and it explores the multiple population (MP) phenomenon in Galactic bulg…

CAPOS: the bulge Cluster APOgee Survey IX. Spectroscopic Analysis of the Bulge Globular Cluster Terzan 2

Macarena Uribe, Sandro Villanova, Douglas Geisler +5

We present the first detailed spectroscopic analysis of the heavily extincted bulge globular cluster Terzan 2 (Ter 2) based on high-resolution near-infrared spectra obtained as par…

Revealing the Origins of Galactic Globular Clusters via Their Mg-Al Abundances

Shihui Lin, Baitian Tang, Genghao Liu +4

Many Galactic globular clusters (GCs) originated in diverse host galaxies before being subsequently incorporated into the Milky Way through hierarchical galaxy assembly. Identifyin…

CAPOS: The bulge Cluster APOgee Survey VII. First detailed chemical analysis of NGC 6316

Heinz Frelijj, Danilo González-Díaz, Douglas Geisler +3

As part of the bulge Cluster APOgee Survey (CAPOS), high-resolution, high Signal-to-Noise Ratio Near-Infrared spectroscopy, we aim to conduct the most robust chemical study to date…
