Recent studies of warp kinematics using Gaia DR2 data have produced detections of warp precession for the first time, which greatly exceeds theoretical...

PublicationA Tale of Two Disks: Mapping the Milky Way with the Final Data Release of APOGEE
We present new maps of the Milky Way disk showing the distribution of metallicity ([Fe/H]), α-element abundances ([Mg/Fe]), and stellar age, using a sample of...

PublicationChemical Cartography with APOGEE: Mapping Disk Populations with a 2-process Model and Residual Abundances
We apply a novel statistical analysis to measurements of 16 elemental abundances in 34,410 Milky Way disk stars from the final data release (DR17) of APOGEE-2...

PublicationDiagonal Ridge Pattern of Different Age Populations Found in Gaia-DR2 with LAMOST Main-sequence Turnoff and OB-type Stars
We revisit the diagonal ridge feature (diagonal distributions in the R, v φ plane) found in Gaia and present a timing analysis for it between Galactocentric...

PublicationEvidence for Population-dependent Vertical Motions and the Long-lived Nonsteady Lopsided Milky Way Warp
We present a Galactic disk vertical velocity analysis using OB type stars (OB stars), red clump (RC) stars, and main-sequence turnoff (MSTO) stars with...

PublicationExploring the Galactic Warp through Asymmetries in the Kinematics of the Galactic Disk
Previous analyses of large databases of Milky Way stars have revealed the stellar disk of our Galaxy to be warped and that this imparts a strong signature on...

PublicationMapping the Milky Way Disk with Gaia DR3: 3D Extended Kinematic Maps and Rotation Curve to ≈30 kpc
We apply a statistical deconvolution of the parallax errors based on Lucy's inversion method (LIM) to the Gaia DR3 sources to measure their 3D velocity...
