DESI K-giant catalog identifies Aleph, Sagittarius, GSE, Cetus-Palca and Orphan-Chenab, then shows residual halo high-angular-momentum stars have bimodal MDFs unlike GSE or Sagittarius.
A two-wave radial corrugation model fitted to LAMOST and Gaia data reproduces the observed periodic radial velocity variations and explains the inner-outer disk transition in the Milky Way.
