The Gaia mission has triggered major developments in the field of Galactic dynamics in
recent years, which we discuss in this review. The structure and kinematics of all Galactic …

Context. Several authors have recently applied Jeans modelling to Gaia-based datasets to
infer the circular velocity curve for the Milky Way. These works have consistently found …

We measure the line-of-sight accelerations of 26 binary pulsars due to the Milky Way's
gravitational potential, and produce a three-dimensional map of the acceleration field of the …

Galaxies are not in a dynamical steady state. They continually undergo perturbations, eg,
from infalling dwarf galaxies and dark-matter substructure. After a dynamical perturbation …

The gas distribution in galaxies is smooth on large scales, but is usually time-dependent and
inhomogeneous on smaller scales. The time-dependence originates from processes such …

Warps are common vertical asymmetries that appear in the outer parts of the galactic discs,
bending one part upwards and the other downwards. Many mechanisms can trigger warp …
