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…

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 Originally defined about 80 years ago, their historical membership lists have been superseded thank…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…

Rediscovering the Milky Way with an orbit superposition approach and APOGEE data V. The disc growth and history of star formation

Bridget Ratcliffe, Sergey Khoperskov, Nathan Lee +8

The Milky Way's (MW's) star formation history (SFH) offers insight into the chronology of its assembly and the mechanisms driving its structural development. In this study, we pres…

Chemical decoding of kinematic substructures in the Galactic halo

A. Mori, P. Di Matteo, S. Salvadori +4

In the hierarchical assembly framework, the accretion history of the Milky Way is crucial to understand its evolution. However, in massive mergers, integrals of motion are not stri…
