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 …

Wide-field imaging and spectroscopy enable a host of astrophysical studies that range from
the largest cosmological scales to the local environment of the Milky Way. Starting in 2000 …

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 …

Abstract We present Dark Energy Spectroscopic Instrument (DESI) observations of the inner
halo of M31, which reveal the kinematics of a recent merger—a galactic immigration event …

We measure homogeneous distances to M31 and 38 associated stellar systems (− 16.8≤
MV≤− 6.0), using time-series observations of RR Lyrae stars taken as part of the Hubble …

We present the JWST Resolved Stellar Populations Early Release Science (ERS) program.
We obtained 27.5 hr of NIRCam and NIRISS imaging of three targets in the Local Group …

We use Gaia DR2 astrometric and photometric data, published radial velocities and mesa
models to infer distances, orbits, surface gravities, and effective temperatures for all ultra …

Abstract The Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) is constructing
a wide-field map of the resolved stellar populations in the extended halos of these two …

We have conducted a systematic search around the Milky Way (MW) analog NGC 253 (D=
3.5 Mpc), as a part of the Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) …
