Young giant stars reveal a flaring Milky Way disc with 3.5 kpc radial scale and extended spiral arms including a curved Perseus segment and a new Scutum-associated feature.
The Milky Way stellar disk shows a broken radial density profile with four components, azimuthal dependence, inner and outer flaring, and a density-metallicity bump possibly from radial migration.
A new clustering algorithm applied to orbital frequencies yields a dynamical age of 6.8 ± 0.8 Gyr for the Helmi stream.
Optimized filters centered at 3920-3960 Angstrom yield metallicity estimates with 0.18-0.39 dex precision down to [Fe/H] ~ -4 for metal-poor stars from Gaia XP spectra, enabling a catalog of 14.5 million such stars.
The Sagittarius dwarf progenitor had a metallicity gradient of roughly -0.3 dex per kpc prior to infall.
A homogeneous catalogue of age, [Fe/H], heliocentric distance and E(G_BP-G_RP) for 5056 open clusters is produced from uniform Bayesian nested sampling of Gaia DR3 CMDs against PARSEC isochrones with physically motivated priors.
