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 review the recent theoretical and observational developments concerning the interaction
of the Large Magellanic Cloud (LMC) with the Milky Way and its neighbourhood. An …

ABSTRACT The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure
the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger …

Previous studies based on the analysis of Gaia DR2 data have revealed that accreted stars,
possibly originating from a single progenitor satellite, are a significant component of the halo …

Abstract The Large Magellanic Cloud is the most massive satellite galaxy of the Milky Way,
with an estimated mass exceeding a tenth of the mass of the Milky Way,,,–. Just past its …

We measure the total stellar halo luminosity using red giant branch (RGB) stars selected
from Gaia data release 2. Using slices in magnitude, colour, and location on the sky, we …

Halo stars orbit within the potential of the Milky Way, and hence their kinematics can be used
to understand the underlying mass distribution. However, the inferred mass distribution …

We present an analysis of the large-scale structure of the halo of the Andromeda galaxy,
based on the Pan-Andromeda Archeological Survey (PAndAS), currently the most complete …

Galaxy masses play a fundamental role in our understanding of structure formation models.
This review addresses the variety and reliability of mass estimators that pertain to stars, gas …

We measure the orbital properties of halo stars using seven-dimensional information
provided by Gaia and the Sloan Digital Sky Survey. A metal-rich population of stars, present …
