Reconstructing the origin of black hole mergers using sparse astrophysical models
V. Gayathri, Giuliano Iorio, Hiromichi Tagawa +8
The astrophysical origin of binary black hole mergers discovered by LIGO and Virgo remains uncertain. Efforts to reconstruct the processes that lead to mergers typically rely on ei…

GW231123: Likely a product of successive mergers from stellar-mass black holes
Yin-Jie Li, Shao-Peng Tang, Ling-Qin Xue +1
GW231123 is an exceptionally massive binary black hole (BBH) merger with unusually high component spins. Such extreme properties challenge conventional stellar evolution models pre…

What Determines the Maximum Mass of AGN-assisted Black Hole Mergers?
LingQin Xue, Hiromichi Tagawa, Zoltan Haiman +1
The origin of merging binary black holes detected through gravitational waves remains a fundamental question in astrophysics. While stellar evolution imposes an upper mass limit of…
