The lowest luminosity (L) Milky Way satellite galaxies represent the extreme lower limit of the
galaxy luminosity function. These ultra-faint dwarfs are the oldest, most dark matter …

We review the recent theoretical and observational developments concerning the interaction
of the Large Magellanic Cloud (LMC) with the Milky Way and its neighbourhood. An …

We assemble a catalogue of candidate Sagittarius stream members with 5D and 6D phase-
space information, using astrometric data from Gaia DR2, distances estimated from RR …

We present results from the" Mint" resolution DC Justice League suite of Milky Way–like
zoom-in cosmological simulations, which extend our study of nearby galaxies down into the …

We combine Gaia early data release 3 astrometry with accurate photometry and utilize a
probabilistic mixture model to measure the systemic proper motion of 52 dwarf spheroidal …

Aims. We perform a comprehensive determination of the systemic proper motions of 74
dwarf galaxies and dwarf galaxy candidates in the Local Group based on Gaia early data …

We present the discovery of DELVE 6, an ultra-faint stellar system identified in the second
data release of the DECam Local Volume Exploration (DELVE) survey. Based on a …

Abstract The population of Milky Way (MW) satellites contains the faintest known galaxies
and thus provides essential insight into galaxy formation and dark matter microphysics. Here …

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 …

Satellite galaxies are predicted to generate gravitational density wakes as they orbit within
the dark matter (DM) halos of their hosts, causing their orbits to decay over time. The recent …
