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 …

We present the first detailed comparison of populations of dwarf galaxy stellar streams in
cosmological simulations and the Milky Way. In particular, we compare streams identified …

Abstract In the Λ-Cold Dark Matter model of the universe, galaxies form in part through
accreting satellite systems. Previous works have built an understanding of the signatures of …

Observational studies are finding stars believed to be relics of the earliest stages of
hierarchical mass assembly of the Milky Way (ie proto-galaxy). In this work, we contextualize …

Understanding the physical mechanism behind the formation of a corotating thin plane of
satellite galaxies, like the one observed around the Milky Way (MW), has been challenging …

Stellar chemical abundances and kinematics provide key information for recovering the
assembly history of galaxies. In this work we explore the chemo-chrono-kinematics of …

Accreted stellar populations are comprised of the remnants of destroyed galaxies, and often
dominate the 'stellar haloes' of galaxies such as the Milky Way (MW). This ensemble of …

Theory suggests that mergers play an important role in shaping galactic discs and stellar
haloes, which was observationally confirmed in the Milky Way (MW) thanks to Gaia data. In …

From the chemodynamical properties of tidal debris in the Milky Way, it has been inferred
that the dwarf satellites that have been disrupted had different chemical abundances from …

The dynamics of the merger of a dwarf disc galaxy with a massive spiral galaxy of the Milky
Way type were studied in detail. The remnant of such interaction after numerous crossings of …
