A cosmological simulation with tidally compressive cluster formation and compact-object heating yields globular cluster populations consistent with observations.
Bi-CFM learns bidirectional mappings between initial and final state distributions to solve ill-posed inverse problems in chaotic systems, reporting metric improvements and speedups on Lorenz variants plus conservation-respecting results on three-body and globular cluster data.
Koposov 2 is an ancient, extremely metal-poor, compact stellar system best explained as a dissolving globular cluster, not a dwarf galaxy.
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.
Mutual information analysis of TNG50 simulations shows gravitational potential and total energy retain merger mass and infall time information longest, while radial velocity loses it within ~5 Gyr, with washout depending on radius, merger age, and mass.
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.
300S stellar stream exhibits three density peaks, smooth width variations, a possible 4.7 degree gap, and a kink modeled as resulting from Large Magellanic Cloud interaction across its full known footprint.
N-body simulation of a major merger shows M31's extended rotating stellar disc as a stretched and warped remnant of the progenitor disc extending beyond 40 kpc.
Star clusters forming in cosmic filaments at z≈7.6 are systematically slow rotators, and a gas-rich subset overlaps the kinematic and density locus of Milky Way globular clusters, making them plausible proto-globular clusters.
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.
VLT/FLAMES spectroscopy confirms 157 ω Centauri members at 93% success and traces tidal-tail debris to 3.2 deg with kinematics and metallicities continuous into the Fimbulthul stream.
Simulations show that observed rotation in 13.5-Gyr-old alpha-rich stars constrains the Gaia-Sausage-Enceladus merger to mass ratios below 1:4, with interaction and starburst times both near 11 Gyr.
TNG50 simulations of 98 Milky Way analogues find GSE-like debris in 32 cases, with two-merger GSEs in one third; single- and two-merger cases differ in median infall time (5.9 vs 10.7 Gyr ago), abundances, and star-formation histories.
High-precision analysis of TYC 6044-714-1 favors s+r nucleosynthesis over i-process models, which require implausible conditions and mismatch Ba isotopes.
Metallicity peaks in globular clusters and circumgalactic clouds match across cosmic time and are reproduced by forming 3 million solar mass clusters during four enrichment stages of 10^8 solar mass clouds.
