Assembling GW231123 in Star Clusters through the Combination of Stellar Binary Evolution and Hierarchical Mergers
GW231123 is the most massive binary black hole (BBH) merger detected to date by the LIGO–Virgo–KAGRA collaboration. With at least one black hole (BH) in the upper mass gap and both BHs exhibiting high spins ( χ _1,2 ≳ 0.8), this event challenges standard isolated binary evolution models. A compelli...
