We present a simple method for fitting parametrized mass models of the Milky Way to observational constraints. We take a Bayesian approach which allows us to take into account input from photometric and kinematic data, and expectations from theoretical modelling. This provides us with a best-fitting model, which is a suitable starting point for dynamical modelling. We also determine a probability density function on the properties of the model, which demonstrates that the mass distribution of…

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 that

The Milky Way system in Λ cold dark matter cosmological simulations

We apply a semi-analytic galaxy formation model to two high-resolution cosmological N-body simulations to investigate analogues of the Milky Way system. We select these according to observed

Models for the 3D axisymmetric gravitational potential of the Milky Way galaxy - A detailed modelling of the Galactic disk

Aims. Galaxy mass models based on simple and analytical functions for density and potential pairs have been widely proposed in the literature. Disk models that are constrained solely by kinematic

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 the

The mass of the Milky Way from satellite dynamics

We present and apply a method to infer the mass of the Milky Way (MW) by comparing the dynamics of MW satellites to those of model satellites in the eagle cosmological hydrodynamics simulations. A

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 modeling


We present improved estimates of several global properties of the Milky Way, including its current star formation rate (SFR), the stellar mass contained in its disk and bulge+bar components, as well

The milky way total mass profile as inferred from Gaia DR2

We determine the Milky Way (MW) mass profile inferred from fitting physically motivated models to the Gaia DR2 Galactic rotation curve and other data. Using various hydrodynamical simulations of

The structure of the Milky Way based on unWISE 3.4 μm integrated photometry

We present a detailed analysis of the Galaxy structure using an unWISE wide-field image at $3.4\,\mu$m. We perform a 3D photometric decomposition of the Milky Way taking into account (i) the

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 structure



ΛCDM-based Models for the Milky Way and M31. I. Dynamical Models

We apply standard disk formation theory with adiabatic contraction within cuspy halo models predicted by the standard cold dark matter (ΛCDM) cosmology. The resulting models are confronted with the

Mass models of the Milky Way

The proposition that flat rotation curves arise because galaxies have physically distinct haloes rather than outwards-increasing mass-to-light ratios is called into question.

The present and future mass of the Milky Way halo

A simple model for the Milky Way halo is presented. It has a flat rotation curve in the inner regions, but the density falls off sharply beyond an outer edge. This truncated, flat rotation curve (TF)

The Accretion Origin of the Milky Way’s Stellar Halo

We have used data from the Sloan Digital Sky Survey (SDSS) Data Release 5 to explore the overall structure and substructure of the stellar halo of the Milky Way using ~4 million color-selected


We report new precision measurements of the properties of our Galaxy’s supermassive black hole. Based on astrometric (1995-2007) and radial velocity (RV; 2000-2007) measurements from the W. M. Keck

The uncertainty in Galactic parameters

We reanalyse the measurements of parallax, proper motion and line-of-sight velocity for 18 masers in high-mass star-forming regions presented by Reid et al. We use a likelihood analysis to

Dynamical Blueprints for Galaxies

We present an axisymmetric, equilibrium model for late-type galaxies which consists of an exponential disk, a Sérsic bulge, and a cuspy dark halo. The model is specified by a phase-space distribution

Masses for the Local Group and the Milky Way

We use the very large Millennium Simulation of the concordance Lambda cold dark matter cosmogony to calibrate the bias and error distribution of Timing Argument estimators of the masses of the Local

The Milky Way’s Circular Velocity Curve to 60 kpc and an Estimate of the Dark Matter Halo Mass from the Kinematics of ~2400 SDSS Blue Horizontal-Branch Stars

We derive new constraints on the mass of the Milky Way’s dark matter halo, based on 2401 rigorously selected blue horizontal-branch halo stars from SDSS DR6. This sample enables construction of the

The Vertical Distribution and Kinematics of H i and Mass Models of the Galactic Disk

We present full modeling of tangent point emission of HI as seen in the 21 cm transition in the inner Galaxy ($R \simeq 3-8 \kpc$). The model used takes into account emission from a large path length
