Bar-induced migration can move ω Cen from the GSE phase-space region, but requires Ω_b ≲ 26 km s^{-1} kpc^{-1}, challenging consensus on the bar speed.
Bulge Fossil Fragments are estimated to generate 15-250 times more binary black hole mergers than typical globular clusters, marking them as a new class of gravitational wave sources.
CRIRES+ spectra of 30 RGB stars in Liller 1 reveal multi-metallicity sub-populations with abundance trends matching the bulge field and Terzan 5, indicating in-situ formation rather than globular-cluster origin.
N-body simulations show that mutual interactions between Terzan 2, 4, and 5 raise mass-loss rates for the smaller clusters and drive prolate deformations absent in isolated runs.

Dynamical evolution of Milky Way globular clusters on the cosmological timescale II. Terzan 2, 4, and 5 mass loss and collision tracking
N-body simulations show that mutual interactions between Terzan 2, 4, and 5 raise mass-loss rates for the smaller clusters and drive prolate deformations absent in isolated runs.
