The Gaia mission has revolutionized our view of the Milky Way and its satellite citizens. The
field of Galactic Archaeology has been piecing together the formation and evolution of the …

The hierarchical model of galaxy formation predicts that the Milky Way halo is populated by
tidal debris of dwarf galaxies and globular clusters. Due to long dynamical times, debris from …

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 …

Satellites orbiting disk galaxies can induce phase space features such as spirality, vertical
heating and phase-mixing in their disks. Such features have also been observed in our own …

Aims. We aim to demonstrate the scientific potential of the Gaia Early Data Release 3
(EDR3) for the study of different aspects of the Milky Way structure and evolution and we …

We investigate the inner regions of the Milky Way using data from APOGEE and Gaia EDR3.
Our inner Galactic sample has more than 26 500 stars within| X Gal|< 5 kpc,| Y Gal|< 3.5 …

Context. Gaia's third data release provides radial velocities for 33 million stars and
spectroscopically derived atmospheric parameters for more than 5 million targets. When …

In this work, we present two new∼ 109 particle self-consistent simulations of the merger of a
Sagittarius-like dwarf galaxy with a Milky Way (MW)-like disc galaxy. One model is a violent …

We use the photometric metallicities provided by the panoramic Pristine survey to study the
veracity and derive the metallicities of the numerous stellar streams found by the application …

In order to understand the roles of metal flows in galaxy formation and evolution, we analyse
our self-consistent cosmological chemodynamical simulation of a Milky Way like galaxy …
