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 …

We review scenarios in which the particles that account for the Dark Matter (DM) in the
Universe interact only through their couplings with the Higgs sector of the theory, the so …

Our position inside the Galactic disc has previously prevented us from establishing an
accurate rotation curve (RC). The advent of Gaia and its third data release (Gaia DR3) made …

Many aspects of the large-scale structure of the Universe can be described successfully
using cosmological models in which 27±1% of the critical mass-energy density consists of …

ABSTRACT 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 …

We measure the circular velocity curve vc (R) of the Milky Way with the highest precision to
date across Galactocentric distances of 5≤ R≤ 25 kpc. Our analysis draws on the six …

Abstract agama is a publicly available software library for a broad range of applications in
the field of stellar dynamics. It provides methods for computing the gravitational potential of …

The vertical structure and dynamics of stars in our local Galactic neighbourhood contains
much information about the local distribution of visible and dark matter and of perturbations …

ABSTRACT I describe the design, implementation, and usage of galpy, a python package for
galactic-dynamics calculations. At its core, galpy consists of a general framework for …

Abstract The Local Group galaxies offer some of the most discriminating tests of models of
cosmic structure formation. For example, observations of the Milky Way (MW) and …
