Rapid intermediate-mass black hole formation via runaway mergers of black holes
Yining Sun, Long Wang
Observations indicate that supermassive black holes (SMBHs) in high-redshift galaxies formed on timescales far shorter than classical growth models allow. One hypothesis suggests i…
Double Compact Binary Merger Rate Density in Open Star Clusters: Black Holes, Neutron Stars, and White Dwarfs
Savannah Cary, Michiko Fujii, Long Wang +1
Studying compact-object binary mergers in star clusters is crucial for understanding stellar evolution and dynamical interactions in galaxies. Open clusters in particular are more…
Compact Binary Formation in Open Star Clusters III: Probability of Binary Black Holes Hidden in Gaia Black Hole Binary
Ataru Tanikawa, Long Wang, Michiko S. Fujii +3
The Gaia mission and its follow-up observations have discovered a few candidates of non-interacting single black holes (BHs) and visible stars, Gaia BH1, BH2, and BH3, collectively…
Detection for Intermediate-mass Binary Black Holes in Population III Star Clusters with TianQin
Hanzhang Wang, Shuai Liu, Han Wang +3
Context. Population III star clusters are predicted to form in unenriched dark matter halos. Direct N-body simulation of Pop III clusters implies the possible formation and merger…
