When bars and spirals conspire: recurrent build-up of the nuclear regions of disc galaxies
Tristan Boin, Sergey Khoperskov, Paola Di Matteo +6
The assembly history of the central regions of disc galaxies is regulated by dynamical processes that trigger gas infall events, leading to active star formation in nuclear stellar…
Globular Clusters in the Time of the JWST. I. Survey Design and First Results on Multiple Populations and Beyond
A. P. Milone, A. F. Marino, G. Cordoni +25
Globular clusters (GCs) host multiple stellar populations with distinct chemical compositions, but their properties among very low-mass stars remain poorly constrained. The James W…
The chemo-dynamical complexity of ω Centauri: different kinematics for different populations
G. Pagnini, P. Bianchini, P. Di Matteo +1
The origin of ω Centauri remains one of the key open problems in stellar dynamics and chemical evolution. Its large abundance spreads and multiple populations suggest a formation h…
ROLLIN': Rotating globular cluster simulations. I. The kinematic evolution of realistic direct N-body models
P. Bianchini, A. L. Varri, A. Askar +2
Internal rotation has emerged as a fundamental feature of globular clusters (GCs), yet its origin and long-term evolution remain poorly understood. We explore the evolution of rota…
A deep HST view of the open cluster NGC2158: binaries, mass functions, and M-dwarf discontinuity
A. V. Marchuk, F. Muratore, A. P. Milone +13
A significant fraction of stars in both the Galactic field and stellar clusters are members of binary systems. Understanding their properties is therefore essential for a comprehen…
Exploring the ultra-faint dwarf Bootes I using JWST and HST: Metallicity distribution and binaries
F. Muratore, M. V. Legnardi, A. P. Milone +8
Ultra-faint dwarf galaxies (UFDs) are among the oldest and most metal-poor stellar systems in the Universe. Their metallicity distribution encodes the fossil record of the earliest…
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 co…

ω}Centauri (ωCen) is the most enigmatic Galactic globular cluster (GC), with unmatched chemical complexity. We combine photometric and spectroscopic catalogs to identify its distin…
The Small Magellanic Cloud through the lens of the James Webb Space Telescope : binaries and mass function within the galaxy outskirts
M. V. Legnardi, F. Muratore, A. P. Milone +8
The stellar initial mass function (IMF) and the fraction of binary systems are fundamental ingredients that govern the formation and evolution of galaxies. Whether the IMF is unive…
Chemical decoding of kinematic substructures in the Galactic halo
