Discovery of new globular clusters in the Sagittarius dwarf galaxy
D. Minniti, V. Ripepi, J. G. Fernández-Trincado +14
Context. Globular clusters (GCs) are witnesses of the past accretion events onto the Milky Way (MW). In particular, the GCs of the Sagittarius (Sgr) dwarf galaxy are important prob…
Confirmation and physical characterization of the new bulge globular cluster Patchick 99 from the VVV and Gaia surveys
E. R. Garro, D. Minniti, M. Gómez +4
Globular clusters (GCs) are important tools to understand the formation and evolution of the Milky Way (MW). The known MW sample is still incomplete, so the discovery of new GC can…
APOGEE discovery of a chemically atypical star disrupted from NGC 6723 and captured by the Milky Way bulge
José G. Fernández-Trincado, Timothy C. Beers, Dante Minniti +26
The central (`bulge') region of the Milky Way is teeming with a significant fraction of mildly metal-deficient stars with atmospheres that are strongly enriched in cyanogen ($^{12}…
VVVX-Gaia Discovery of a Low Luminosity Globular Cluster in the Milky Way Disk
E. R. Garro, D. Minniti, M. Gómez +20
Milky Way globular clusters (MW GCs) are difficult to identify at low Galactic latitudes because of high differential extinction and heavy star crowding. The new deep near-IR image…
The enigmatic globular cluster UKS~1 obscured by the bulge: \textit{H}-band discovery of nitrogen-enhanced stars
José G. Fernández-Trincado, Dante Minniti, Timothy C. Beers +13
The presence of nitrogen-enriched stars in globular clusters provides key evidence for multiple stellar populations (MPs), as has been demonstrated with globular cluster spectrosco…
