The faintest dwarf galaxies

JD Simon - Annual Review of Astronomy and Astrophysics, 2019 - annualreviews.org
The lowest luminosity (L) Milky Way satellite galaxies represent the extreme lower limit of the

Gaia DR2 proper motions of dwarf galaxies within 420 kpc-orbits, Milky Way mass, tidal influences, planar alignments, and group infall

TK Fritz, G Battaglia, MS Pawlowski… - Astronomy & …, 2018 - aanda.org
A proper understanding of the Milky Way (MW) dwarf galaxies in a cosmological context

The orbital histories of Magellanic satellites using Gaia DR2 proper motions

E Patel, N Kallivayalil… - The Astrophysical …, 2020 - iopscience.iop.org
With the release of Gaia DR2, it is now possible to measure the proper motions (PMs) of the
lowest-mass, ultrafaint satellite galaxies in the Milky Way's (MW) halo for the first time. Many …

Accurate masses for dispersion-supported galaxies
