Galactic tides in the Solar System within a non-axisymmetric Milky Way model adjusted to Gaia data

Alexandre Bougakov, Yassin Rany Khalil, Marc Fouchard +4

Context. Galactic tides are external differential forces acting on extended systems immersed in the Galactic potential. They play a key role in the dynamics of comets in the Oort c…

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…

Gaia DR3 high radial velocity stars: Genuine fast-moving objects or outliers?

D. Katz, A. Gómez, E. Caffau +39

The third Gaia data release includes 33.8 million radial velocity measurements, extending to a magnitude of G_RVS = 14. To reach this magnitude limit, spectra were processed down t…

A new Gaia census of OB associations within 1 kpc

Alexis L. Quintana, Nicholas J. Wright, Lilly A. Kormann +6

OB associations are primordial tracers of star formation and Galactic structure. Originally defined about 80 years ago, their historical membership lists have been superseded thank…

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…
