Markov chain Monte Carlo–based Bayesian data analysis has now become the method of
choice for analyzing and interpreting data in almost all disciplines of science. In astronomy …

We perform an extensive review of the numerous studies and methods used to determine
the total mass of the Milky Way. We group the various studies into seven broad classes …

Modern Galactic surveys have revealed an ancient merger that dominates the stellar halo of
our galaxy (Gaia–Sausage–Enceladus, GSE). Using chemical abundances and kinematics …

We derive the mass model of the Milky Way (MW), crucial for Dark Matter (DM) direct and
indirect detection, using recent data and a cored dark matter (DM) halo profile, which is …

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 …

We made new estimates of the Galactic escape speed at various Galactocentric radii using
the latest data release of the RAdial Velocity Experiment (RAVE DR4). Compared to …

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 use a large sample of isolated dark matter halo pairs drawn from cosmological N-body
simulations to identify candidate systems whose kinematics match that of the Local Group …

Motivated by recent observations of the Sagittarius stream, we devise a rapid algorithm to
generate faithful representations of the centroids of stellar tidal streams formed in a …

We explore the connection between galaxies and dark matter haloes in the Milky Way (MW)
and quantify the implications on properties of the dark matter particle and the …
