Dark Galactic Subhalos and the Gaia Snail by Daniel Gilman, Jo Bovy, Neige Frankel, Andrew Benson

“…Perturbations caused by dark subhalos are, on average, orders of magnitude weaker than those caused by luminous satellite galaxies, but the ubiquity of dark halos predicted by cold dark matter makes them a more probable source of strong perturbation to the dynamics of the solar neighborhood. …”
