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…

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…

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…

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…

The chemical enrichment histories across the Milky Way disk

Valeria Cerqui, Misha Haywood, Owain Snaith +2

The variation of metal production over time and its dilution in the interstellar medium depend on the star formation and gas accretion rates. Measuring age-chemistry relations acro…

Quadrupole signature as a kinematic diagnostic to constrain bar properties : implications for the Milky Way

Soumavo Ghosh, Taavet Kalda, Paola Di Matteo +4

The presence of a 'butterfly' or a quadrupole structure in the stellar mean radial velocity () field of the Milky Way is well known from the Gaia and the APOGEE surveys. Pas…
