Nature and nurture: the dynamical ages of in situ and accreted globular clusters in the Milky Way

Eugenio Carretta (INAF - Osservatorio di Astrofisica e Scienza dello Spazio di Bologna) ยท 2026

The bifurcated age-metallicity relation of globular clusters (GCs) in the Milky Way (MW) shows that GCs are either originated in situ or accreted into the Galaxy from former satellites of the MW. The โ€ฆ
