Unveiling Galactic substructures with M Giant stars: A kinematic and chemical study based on LAMOST DR9, Gaia DR3 and APOGEE DR17
Orbit-based clustering of LAMOST DR9 M giants recovers the Milky Way's known merger relics, finds two unclassified groups, and supports the scenario that the Gaia-Enceladus merger heated the primordial high-alpha disk into the Splash.
