Abstract We describe the Milky Way Survey (MWS) that will be undertaken with the Dark
Energy Spectroscopic Instrument (DESI) on the Mayall 4 m telescope at the Kitt Peak …

Modern Galactic surveys have revealed an ancient merger that dominates the stellar halo of
our galaxy (Gaia–Sausage–Enceladus, GSE). Using chemical abundances and kinematics …

Modern theories of galaxy formation predict that the Galactic stellar halo was hierarchically
assembled from the accretion and disruption of smaller systems. This hierarchical assembly …

The Galactic stellar halo is predicted to have formed at least partially from the tidal disruption
of accreted dwarf galaxies. This assembly history should be detectable in the orbital and …

We describe the design and performance of the near-infrared (1.51–1.70 μm), fiber-fed, multi-
object (300 fibers), high resolution (R= λ/Δλ∼ 22,500) spectrograph built for the Apache …

Binospec is a high-throughput, 370 to 1000 nm, imaging spectrograph that addresses two
adjacent 8'by 15'fields of view. Binospec was commissioned in late 2017 at the f/5 focus of …

We present results from MMT/Hectochelle spectroscopy of 390 red giant candidate stars
along the line of sight to the recently discovered Galactic satellite Crater 2. Modeling the joint …

Based on more than four weeks of continuous high-cadence photometric monitoring of
several hundred members of the young cluster NGC 2264 with two space telescopes …

Context. The goal of the Turn-Off Primordial Stars survey (TOPoS) project is to find and
analyse turn-off (TO) stars of extremely low metallicity. To select the targets for spectroscopic …
