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 depends sensitively on assumptions made on the density and the velocity anisotropy profiles of the tracer population. Also, there is a degeneracy between the parameters of the halo and those of the disk or bulge. Most previous attempts that use halo stars have made arbitrary assumptions about these. In this paper… Expand

Abstract The Milky Way, “our” Galaxy, is currently the subject of intense study with many ground-based surveys, in anticipation of upcoming results from the Gaia mission. From this work we have beenExpand
Galactic googly: the rotation-metallicity bias in the inner stellar halo of the Milky Way
The first and second moments of stellar velocities encode important information about the formation history of the Galactic halo. However, due to the lack of tangential motion and inaccurateExpand
The Mass Profile of the Milky Way to the Virial Radius from the Illustris Simulation
We use particle data from the Illustris simulation, combined with individual kinematic constraints on the mass of the Milky Way (MW) at specific distances from the Galactic Centre, to infer theExpand
Spiral arm kinematics for Milky Way stellar populations
We present a new theoretical population synthesis model (the Galaxy model) to examine and deal with large amounts of data from surveys of the Milky Way and to decipher the present and past structureExpand
The mass distribution and gravitational potential of the Milky Way
We present mass models of the Milky Way created to fit observational constraints and to be consistent with expectations from theoretical modelling. The method used to create these models is thatExpand
Estimating the dark matter halo mass of our Milky Way using dynamical tracers
The mass of the dark matter halo of the Milky Way can be estimated by fitting analytical models to the phase-space distribution of dynamical tracers. We test this approach using realistic mockExpand
Joint constraints on the Galactic dark matter halo and Galactic Centre from hypervelocity stars
The mass assembly history of the Milky Way can inform both theory of galaxy formation and the underlying cosmological model. Thus, observational constraints on the properties of both its baryonic andExpand
The Milky Way's Circular Velocity Curve and Its Constraint on the Galactic Mass with RR Lyrae Stars
We present a sample of 1148 ab-type RR Lyrae (RRLab) variables identified from Catalina Surveys Data Release 1, combined with SDSS DR8 and LAMOST DR4 spectral data. We first use a large sample of 860Expand
The mass of our Milky Way
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 according to their modelingExpand
The Galaxy in Context: Structural, Kinematic, and Integrated Properties
Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only galaxy whose formation history can be studied using the full distribution of stars from faint dwarfs toExpand

We present a family of robust tracer mass estimators to compute the enclosed mass of galaxy haloes from samples of discrete positional and kinematical data of tracers, such as halo stars, globularExpand
Very Metal-Poor Outer-Halo Stars with Round Orbits
The orbital motions of halo stars in the Milky Way reflect the orbital motions of the progenitor systems in which they formed, making it possible to trace the mass-assembly history of the Galaxy.Expand
Rotation Curve of the Milky Way out to ~200 kpc
