We continue our series of papers on phase-space distributions of stars in the Milky Way based on photometrically derived metallicities and Gaia astrometry, with...

PublicationDetection of Multiple Phase Space Overdensities of GSE Stars by Orbit Integration
In N-body simulations, nearly radial mergers can form shell-like overdensities in the sky position and phase space (r - v r ) due to the combination of...

PublicationIdentifying RR Lyrae Variable Stars in Six Years of the Dark Energy Survey
We present a search for RR Lyrae stars using the full six-year data set from the Dark Energy Survey covering ∼5000 deg2 of the southern sky. Using a multistage...

PublicationOn the Use of Field RR Lyrae as Galactic Probes. II. A New ΔS Calibration to Estimate Their Metallicity
We performed the largest and most homogeneous spectroscopic survey of field RR Lyraes (RRLs). We secured ≍6300 high-resolution (HR, R ∼ 35,000) spectra for 143...

PublicationOn the Use of Field RR Lyrae as Galactic Probes. III. The α-element Abundances
We provide the largest and most homogeneous sample of α-element (Mg, Ca, Ti) and iron abundances for field RR Lyrae (RRLs; 162 variables) by using high...

PublicationOn the Use of Field RR Lyrae As Galactic Probes: IV. New Insights Into and Around the Oosterhoff Dichotomy
We discuss the largest and most homogeneous spectroscopic data set of field RR Lyrae variables (RRLs) available to date. We estimated abundances using both high...

PublicationOverview of the DESI Milky Way Survey
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...
