The Nephele ecosystem: stars, globular clusters, and stellar streams associated with the progenitor galaxy of Centauri

G. Pagnini, P. Di Matteo, M. Haywood +7

Globular clusters (GCs) and their associated stellar streams are key tracers of the hierarchical assembly history of the Milky Way. Centauri, the most massive and chemically c…

A new classification of ex-situ and in-situ Galactic globular clusters based on a method trained on Milky Way analogues in the TNG50 cosmological simulations

Pierre Boldrini, Paola Di Matteo, Chervin Laporte +3

We present a novel method combining existing cosmological simulations and orbital integration to study the hierarchical assembly of globular cluster (GC) populations in the Milky W…

Simulating nearby disc galaxies on the main star formation sequence II. The gas structure transition in low and high stellar mass discs

Pierrick Verwilghen, Eric Emsellem, Florent Renaud +14

Recent hydrodynamical simulations of isolated barred disc galaxies have suggested a structural change in the distribution of the interstellar medium (ISM) around a stellar mass M$_…

Chemical Abundances in the Nuclear Star Cluster of the Milky Way: alpha-Element Trends and Their Similarities with the Inner Bulge

N. Ryde, G. Nandakumar, M. Schultheis +15

A chemical characterization of the Galactic Center is essential for understanding its formation and structural evolution. Trends of alpha-elements, such as Mg, Si, and Ca, serve as…

Abundance ties: Nephele and the globular cluster population accreted with Cen. Based on APOGEE DR17 and Gaia EDR3

Giulia Pagnini, Paola Di Matteo, Misha Haywood +8

The peculiar Galactic globular cluster Centauri (NGC 5139) has drawn attention for its unique features - such as a high stellar mass and a broad distribution of chemical eleme…
