Galactic haloes in a Λ-CDM universe are predicted to host today a swarm of debris resulting
from cannibalized dwarf galaxies. The chemodynamical information recorded in their stellar …

We combine spectroscopic, photometric, and astrometric information from APOGEE data
release 17 and Gaia early data release 3 to perform a self-consistent characterization of …

We present a new suite of cosmological zoom-in hydrodynamical (spatial resolution)
simulations of Milky-Way mass galaxies to study how a varying mass ratio for a Gaia …

Context. Studies of the element abundances and kinematics of stars belonging to the
Galactic halo have revealed the existence of two distinct populations: accreted stars with a …

ABSTRACT Within a simulated Milky Way-like galaxy, we identify and analyse analogues of
the Gaia-Enceladus (GE), Kraken, and Sequoia mergers that each matches remarkably well …

Context. In an accompanying paper, we present a data-driven method for clustering in
'integrals of motion'space and apply it to a large sample of nearby halo stars with 6D phase …

The assembly history of the Milky Way (MW) is a rapidly evolving subject, with numerous
small accretion events and at least one major merger proposed in the MW's history. Accreted …

Context. The Helmi streams are a kinematic substructure whose progenitor is likely a dwarf
galaxy. Although 20 years have passed since their discovery, it is still unclear whether their …

Relics of ancient accretion events experienced by the Milky Way are predominantly located
within the stellar halo of our Galaxy. However, debris from different objects display …

Magnesium is one of the most important elements in stellar physics as an electron donor; in
Galactic archaeology, magnesium serves to distinguish different stellar populations …
