Our Galaxy, the Milky Way, is a benchmark for understanding disk galaxies. It is the only
galaxy whose formation history can be studied using the full distribution of stars from faint …

Galactic halo gas traces inflowing star-formation fuel and feedback from a galaxy's disk and
is therefore crucial to our understanding of galaxy evolution. In this review, we summarize …

Positional, structural, and dynamical parameters for all dwarf galaxies in and around the
Local Group are presented, and various aspects of our observational understanding of this …

One of the key open questions in extragalactic astronomy is what stops star formation in
galaxies. While it is clear that the cold gas reservoir, which fuels the formation of new stars …

We report the discovery of eight new Milky Way companions in $\sim 1800\;{\mathrm
{deg}}^{2} $ of optical imaging data collected during the first year of the Dark Energy Survey …

We present spectroscopic metallicities of individual stars in seven gas-rich dwarf irregular
galaxies (dIrrs), and we show that dIrrs obey the same mass–metallicity relation as the dwarf …

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 …

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 …

Abstract The Widefield ASKAP L-band Legacy All-sky Blind surveY (wallaby) is a next-
generation survey of neutral hydrogen (H i) in the Local Universe. It uses the widefield, high …

The dwarf spheroidal satellite galaxies of the Milky Way are some of the most dark-matter-
dominated objects known. Due to their proximity, high dark matter content, and lack of …
