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 …

Anomalously high nitrogen-to-oxygen abundance ratios [N/O] are observed in globular
clusters (GCs), among the field stars of the Milky Way (MW), and even in the gas in az≈ 11 …

ABSTRACT The Gaia-Sausage/Enceladus (GS/E) structure is an accretion remnant that
comprises a large fraction of the Milky Way's stellar halo. We study GS/E using high-purity …

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 …

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 …

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 …

Over the next decade, the astronomical community will be commissioning multiple wide-field
observatories well suited for studying stellar halos in both integrated light and resolved stars …

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 …

We construct time-evolving gravitational potential models for a Milky Way–mass galaxy from
the FIRE-2 suite of cosmological-baryonic simulations using basis function expansions …

Dark matter subhalos are predicted to perturb stellar streams; stream morphologies and
dynamics can, therefore, constrain the mass distribution of subhalos. Using FIRE-2 …
