Unveiling the Milky Way with a Gaia DR3 census of OB-type stars within 2 kpc. I. Tracing local Galactic structure, massive star-forming regions and core-collapse supernova progenitors
Alexis L. Quintana, Kiril Maltsev, Eloisa Poggio +10
O- and B-type stars are young and hot, thereby serving as vital tracers of the star formation and spiral arm structure of the Milky Way. At the dusk of the \textit{Gaia} DR3 era, a…
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…
Bar-induced deflection of open cluster tidal tails
Hanna Parul, Laia Casamiquela, Paola Di Matteo +1
We present a systematic study of how the Galactic bar affects the orientation of tidal tails of open clusters and assess the power of tail morphology to constrain the bar's pattern…
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…
Fuzzy dark matter dynamical friction: stalling of globular clusters induced by dynamical heatings
Adrian Szpilfidel, Pierre Boldrini, Jo Bovy +1
We present a new implementation of fuzzy dark matter (FDM) dynamical friction within the galpy framework, enabling orbital integrations of globular clusters (GCs) across a broad ra…
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…
