Chemo-dynamical stratification of the Galactic disc using \emph{Gaia}-ESO open clusters
Casmir O. Obasi, M. Gómez, J. G. Fernández-Trincado +5
Understanding how the Milky Way disc assembled and evolved requires tracing the coupled evolution of stellar chemistry and orbital structure over time. Open clusters, as coeval ste…
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…
A Galactic Self-Portrait: Density Structure and Integrated Properties of the Milky Way Disk
Julie Imig, Jon A. Holtzman, Gail Zasowski +23
The evolution history of the Milky Way disk is imprinted in the ages, positions, and chemical compositions of individual stars. In this study, we derive the intrinsic density distr…
Measuring and modelling the Splash with APOGEE/Gaia and ARTEMIS
Shobhit Kisku, Ricardo P. Schiavon, Andreea S. Font +6
Using combined data from SDSS-IV/APOGEE and Gaia, we study the chemo-dynamical properties of the Splash population in comparison with those of the high-alpha disc. We investigate a…
The VISCACHA Survey: XIII. The extended main-sequence turn-off in intermediate-age low-mass clusters
Stefano Souza, Angeles Pérez-Villegas, Bruno Dias +16
The extended main-sequence turn-off (eMSTO) is a well-known feature observed in young and intermediate-age star clusters, characterized by a significant broadening of the main-sequ…
Open cluster members in APOGEE DR17 I. Dynamics and star members
R. Guerço, D. Souto, J. G. Fernández-Trincado +7
Context. Open clusters (OCs) are groups of stars formed from the same cloud of gas and cosmic dust. They play an important role in studies of star formation and evolution and our u…
SDSS-V LVM: Collisionless Shocks in the Supernova Remnant RCW86
Sumit K. Sarbadhicary, Knox S. Long, John C. Raymond +19
The supernova remnant (SNR) RCW86 is among the few SNRs with Balmer-emission lines containing broad and narrow spectral components that trace fast, non-radiative shocks in partiall…
Sloan Digital Sky Survey-V: Pioneering Panoptic Spectroscopy
Juna A. Kollmeier, Hans-Walter Rix, Conny Aerts +217
The Sloan Digital Sky Survey-V (SDSS-V) is pioneering panoptic spectroscopy: it is the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. SDSS-V is mapping the s…
CAPOS: The bulge Cluster APOgee Survey V. Elemental abundances of the bulge globular cluster HP 1
Lady Henao, Sandro Villanova, Doug Geisler +1
We have performed a detailed abundance analysis of 10 red giant members of the heavily obscured bulge globular cluster HP~1 using high-resolution, high S/N near-infrared spectra co…
Multi-Wavelength characterization of VVVX open clusters
C. O. Obasi, E. R. Garro, J. G. Fernández-Trincado +4
Context. Large-scale surveys across wavelengths, aided by machine learning, have improved the detection of old open clusters in high-extinction Milky Way regions. Aims. We aim to c…
Variable stars in the VVV globular clusters III. RR Lyrae stars in the inner Galactic globular clusters
Javier Alonso-García, Leigh C. Smith, Jason L. Sanders +13
High reddening near the Galactic plane hampers observations and proper characterization of the globular clusters (GCs) located toward the inner regions of the Milky Way. The VISTA…
Abundances of iron-peak elements in 58 bulge spheroid stars from APOGEE
B. Barbuy, A. C. S. Friaça, H. Ernandes +22
Stars presently identified in the bulge spheroid are probably very old, and their abundances can be interpreted as due to the fast chemical enrichment of the early Galactic bulge.…
VVVX survey dusts off a new intermediate-age star cluster in the Milky Way disk
E. R. Garro, D. Minniti, J. Alonso-García +5
Our primary long-term objective is to seek out additional star clusters in the poorly studied regions of the MW. The aim of this pursuit is to finalize the MG's globular and open c…
Over 200 globular clusters in the Milky Way and still none with super-Solar metallicity
E. R. Garro, D. Minniti, J. G. Fernández-Trincado
Many globular clusters (GCs) in the Milky Way (MW) have been studied in recent years, especially in hidden regions such as those of the Galactic bulge. Our main goal is to understa…
Abundances in eight bulge stars from the optical and near-infrared
Patrícia da Silva, B. Barbuy, H. Ernandes +3
Context: The abundances of the -elements are key for understanding the early chemical enrichment of the Galactic bulge. The elements of interest present lines in different wavel…
Signature of systemic rotation in 21 Galactic Globular Clusters from APOGEE-2
Ilaria Petralia, Dante Minniti, José G. Fernández-Trincado +2
Context. Traditionally, Globular Clusters (GCs) have been assumed to be quasi-relaxed non-rotating systems, characterized by spherical symmetry and orbital isotropy. However, in re…
Driving factors behind multiple populations
Ruoyun Huang, Baitian Tang, Chengyuan Li +9
Star clusters were historically considered simple stellar populations, with all stars sharing the same age and initial chemical composition. However, the presence of chemical anoma…
