Koposov 2 is an ancient, extremely metal-poor, compact stellar system best explained as a dissolving globular cluster, not a dwarf galaxy.
ANTARES Galactic Ridge upper limits yield competitive dark-matter annihilation/decay bounds, the first neutrino-based branon constraints, and a negative KM3NeT forecast for the thermal relic cross-section.
The Gaia-Sausage-Enceladus merger occurred 11.2 ± 0.1 Gyr ago, coinciding with the formation of a group of globular clusters and potentially leaving ω Centauri as its remnant, while placing disk formation at z ≳ 4.
Ages from sub-giant stars in the TOPoS sample reveal a multi-modal age-metallicity relation in the Galactic halo with peaks linked to halo, thick-disc and thin-disc components, indicating mergers were important until 8 Ga ago.
N-body simulations of the Milky Way-GSE merger indicate that halo and merger-formed globular clusters largely retain orbital energy, allowing most GSE-linked GCs to trace accretion events in the E-Lz plane.
NGC 6791 has an age of 8.46 ± 0.66 Gyr, [Fe/H] = +0.280 ± 0.079, and other parameters that favor an inner-Galaxy origin followed by outward migration.
NGC 6553 is a metal-rich globular cluster that formed in situ in the Galactic bulge, shown by its abundance patterns, multiple populations, and chemical DNA tests.

The Last Galactic Firework: Timing the last significant merger with stars, globular clusters and $\omega$Centauri
The Gaia-Sausage-Enceladus merger occurred 11.2 ± 0.1 Gyr ago, coinciding with the formation of a group of globular clusters and potentially leaving ω Centauri as its remnant, while placing disk formation at z ≳ 4.

TOPoS VII. Age-metallicity relation in the Galactic halo and assembly of the Milky Way
Ages from sub-giant stars in the TOPoS sample reveal a multi-modal age-metallicity relation in the Galactic halo with peaks linked to halo, thick-disc and thin-disc components, indicating mergers were important until 8 Ga ago.

The accretion history of the Milky Way V. The kinematics of most globular clusters trace the merger epochs
N-body simulations of the Milky Way-GSE merger indicate that halo and merger-formed globular clusters largely retain orbital energy, allowing most GSE-linked GCs to trace accretion events in the E-Lz plane.
