A Lagrangian model with mild radial gas flows (1.5 km/s) simultaneously reproduces the Milky Way's [O/Fe]-[Fe/H] distribution, stellar surface density profile, abundance gradients, and age-abundance relations under a two-infall scenario.

Kinematic measurements in the inner Milky Way show vertex deviation and anisotropy consistent with a nuclear bar oriented at approximately 60-75 degrees to the line of sight.
Chemical mixture modeling of Gaia and APOGEE stars indicates that most kinematic halo substructures are contaminated with Gaia-Sausage/Enceladus debris and heated disc stars, so no halo substructure is a chemically pure population.
Planar very metal-poor stars exhibit chemical homogeneity and dwarf-galaxy-like abundance ratios, supporting origin from one ancient accreted system tentatively called Loki.
Gaia DR3 data shows the Milky Way bar pattern speed is biased high by 14.4 km s^{-1} kpc^{-1}, with a bias-corrected estimate of 29.3 ± 2.3 km s^{-1} kpc^{-1}.
AT 2025abao is the fourth LRN in M31, showing a plateau light curve, canonical spectroscopic evolution from hot continuum with Balmer lines to cool molecular bands, and an AGB progenitor whose IR SED is reported for the first time.

Chemical evolution of the Milky Way disc with radial gas flows: a Lagrangian approach
A Lagrangian model with mild radial gas flows (1.5 km/s) simultaneously reproduces the Milky Way's [O/Fe]-[Fe/H] distribution, stellar surface density profile, abundance gradients, and age-abundance relations under a two-infall scenario.

Chemical decoding of kinematic substructures in the Galactic halo
Chemical mixture modeling of Gaia and APOGEE stars indicates that most kinematic halo substructures are contaminated with Gaia-Sausage/Enceladus debris and heated disc stars, so no halo substructure is a chemically pure population.
