| Unveiling the origin of Galactic globular clusters: insights from chemical abundances. |
| Reconstructing the formation and assembly of the stellar components within our Galaxy is a fundamental goal of Galactic archaeology. The advent of the Gaia astrometric mission has revolutionized our understanding of the Milky Way, providing precise measurements of stellar positions, distances, and motions for millions of stars. Complementing Gaia's efforts, spectroscopic surveys such as the APOGEE survey have furnished detailed chemical abundances that serve as powerful indicators, as they remain relatively conserved throughout stellar evolution and so reflecting the birth environment of stars. Globular clusters, being among the oldest stellar systems within the Milky Way, offer a unique perspective into its formation and evolution. These can be classified into two distinct scenarios: those that formed in-situ within the Milky Way and those acquired through mergers with satellite galaxies. In this talk, we present our work that combines the precise astrometric data from Gaia with the detailed spectroscopic measurements from APOGEE to probe the origins of Galactic globular clusters spanning from the bulge to the halo regions. By analyzing the chemical patterns within these globular clusters, we aim to identify similarities and differences that may unveil distinct signatures associated with their formation locations, ultimately shedding light on the formation history of the Milky Way. |
