Astronomical observations reveal a major deficiency in our understanding of physics—the
detectable mass is insufficient to explain the observed motions in a huge variety of systems …

We present the final sample of the Exploration of Local VolumE Satellites (ELVES) survey, a
survey of the dwarf satellites of a nearly volume-limited sample of Milky Way (MW)− like …

The tip of the red giant branch (TRGB) provides a luminous standard candle for constructing
distance ladders to measure the Hubble constant. In practice, its measurements via edge …

Driven by the increasingly complete observational knowledge of systems of satellite
galaxies, mutual spatial alignments and relations in velocities among satellites belonging to …

Quantifying the connection between galaxies and their host dark matter halos has been key
for testing cosmological models on various scales. Below M⋆∼ 10 9 M⊙, such studies have …

We use GRUMPY, a simple regulator-type model for dwarf galaxy formation and evolution,
to forward model the dwarf galaxy satellite population of the Milky Way (MW) using the …

Isolated dwarf galaxies usually exhibit robust star formation but satellite dwarf galaxies are
often devoid of young stars, even in Milky Way–mass groups. Dwarf galaxies thus offer an …

We report the discovery of Tucana B, an isolated ultra-faint dwarf galaxy at a distance of D=
1.4 Mpc. Tucana B was found during a search for ultra-faint satellite companions to the …

We present a new observation of satellite galaxies around seven Milky Way (MW)–like
galaxies located outside of the Local Group (LG) using Subaru/Hyper Suprime-Cam imaging …

Dwarf galaxies have been extensively studied in the Local Group, in nearby groups, and
selected clusters, giving us a robust picture of their global stellar and dynamical properties …
