Impact of Ly radiation force on super-Eddington accretion onto a massive black hole
Takuya Mushano, Takumi Ogawa, Ken Ohsuga +2
The viability of super-Eddington accretion remains a topic of intense debate, crucial for understanding the formation of supermassive black holes in the early universe. However, th…
Merger rate density of binary black holes through isolated Population I, II, III and extremely metal-poor binary star evolution
Ataru Tanikawa, Takashi Yoshida, Tomoya Kinugawa +4
We investigate the formation of merging binary black holes (BHs) through isolated binary evolution, performing binary population synthesis calculations covering an unprecedentedly…
Signatures of Hierarchical Mergers in Black Hole Spin and Mass distribution
Hiromichi Tagawa, Zoltán Haiman, Imre Bartos +2
Recent gravitational wave (GW) observations by LIGO/Virgo show evidence for hierarchical mergers, where the merging BHs are the remnants of previous BH merger events. These events…
Mass-gap Mergers in Active Galactic Nuclei
Hiromichi Tagawa, Bence Kocsis, Zoltan Haiman +3
The recently discovered gravitational wave sources GW190521 and GW190814 have shown evidence of BH mergers with masses and spins that could be outside of the range expected from is…
Eccentric Black Hole Mergers in Active Galactic Nuclei
Hiromichi Tagawa, Bence Kocsis, Zoltan Haiman +3
The astrophysical origin of gravitational wave (GW) transients is a timely open question in the wake of discoveries by LIGO/Virgo. In active galactic nuclei (AGNs), binaries form a…
