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…

Infrared photometry and CaT spectroscopy of the most metal-poor in-situ globular cluster VVV-CL001

W. Haro Moya, C. Moni Bidin, M. C. Parisi +11

Globular clusters in the Galactic bulge are difficult to study due to high extinction and severe crowding. VVV-CL001 is an old, metal-poor, and fast cluster in the inner bulge, who…

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…

CAPOS: The bulge Cluster APOgee Survey VIII. Final ASPCAP results for all clusters

Doug Geisler, Cesar Muñoz, Sandro Villanova +12

Bulge globular clusters(BGCs) are exceptional tracers of the formation and chemodynamical evolution of this oldest Galactic component. However, until now, observational difficultie…

The CHIMERA Survey: The first CO detection in Leo T, the lowest mass known galaxy still hosting cold molecular gas

Vicente Villanueva, Matías Blaña, Alberto D. Bolatto +13

We report the first CO detection in Leo T, representing the most extreme observation of carbon monoxide molecules in the lowest stellar mass gas-rich dwarf galaxy ($\sim…
