ROLLIN': Rotating globular cluster simulations II. The complex morphology of globular clusters driven by multi-scale dynamics
Arn Marklund, Paolo Bianchini, Anna Lisa Varri +2
Globular clusters (GCs) are inherently non-spherical systems that in many cases show internal rotation. Typically, rotation is considered the main driver of GC morphology; however,…
The chemo-dynamical complexity of Ï Centauri: different kinematics for different populations
G. Pagnini, P. Bianchini, P. Di Matteo +1
The origin of Ï Centauri remains one of the key open problems in stellar dynamics and chemical evolution. Its large abundance spreads and multiple populations suggest a formation…
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…
Asymmetries in stellar streams induced by a galactic merger
Claire Guillaume, Florent Renaud, Nicolas F. Martin +6
Stellar streams are sensitive to perturbations from, e.g., giant molecular clouds, bars and spiral arms, infalling dwarf galaxies, or globular clusters which can imprint gaps, clum…
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…
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…
