A ~1 solar-mass main-sequence star with supersolar metallicity has been traced back to the galactic center as a hypervelocity star ejected by the Hills mechanism.
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.
RR Lyrae stars yield metallicity measurements for Milky Way halo substructures including Gaia Sausage/Enceladus at [Fe/H] = -1.57 dex, with some features like ED-1 showing disk contamination and others like Shiva and Shakti suggested as in-situ.
Five halo substructures (disk, Splash, GSE, Thamnos1, Thamnos2) are recovered with distinct chemo-dynamical properties supporting extragalactic origins.
Stellar halos act as transition regions between bright central galaxies and intracluster light, with strong mass correlations, similar colors that redden over time, and a shrinking metallicity gap from 0.4 dex at z=2 to 0.1 dex today.
Using 8D chemical clustering on APOGEE DR17 and kinematic matching to e-TidalGCs simulations, the authors report 470 ω Cen-like stars including 6 kinematically consistent with its stream and additional links to streams from five other clusters, supporting a common disrupted progenitor.
