Abstract The Milky Way halo was predominantly formed by the merging of numerous
progenitor galaxies. However, our knowledge of this process is still incomplete, especially in …

We describe a public data release of the FIRE-2 cosmological zoom-in simulations of galaxy
formation (available at http://flathub. flatironinstitute. org/fire) from the Feedback In Realistic …

We report the kinematic, orbital, and chemical properties of 12 stellar streams with no
evident progenitors using line-of-sight velocities and metallicities from the Southern Stellar …

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 …

Context. It has been observed that several Milky Way (MW) satellite dwarf galaxies are
distributed along a coherent planar distribution known as the vast polar structure (VPOS) …

Context. Reconstructing how all the stellar components of the Galaxy formed and assembled
over time by studying the properties of the stars that form it is the aim of Galactic …

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 …

In the Gaia era it is increasingly apparent that traditional static, parameterized models are
insufficient to describe the mass distribution of our complex, dynamically evolving Milky Way …

The orbits of satellite galaxies encode rich information about their histories. We investigate
the orbital dynamics and histories of satellite galaxies around Milky Way (MW)-mass host …
