Black hole mergers of AGN origin in LIGO/Virgo's O1-O3a observing periods
V. Gayathri, Y. Yang, H. Tagawa +2
The origin of the black hole mergers detected by LIGO and Virgo remains an open question. While the unusual mass and spin of a few events constrain their possible astrophysical for…
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…
Accretion-Induced Collapse of Neutron Stars in the Disks of Active Galactic Nuclei
Rosalba Perna, Hiromichi Tagawa, Zoltan Haiman +1
The disks of active galactic nuclei (AGNs) have emerged as a rich environment for the evolution of stars and their compact remnants. The very dense medium favors rapid accretion, w…
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…
Black Hole Formation in the Lower Mass Gap through Mergers and Accretion in AGN Disks
Y. Yang, V. Gayathri, I. Bartos +3
The heaviest neutron stars and lightest black holes expected to be produced by stellar evolution leave the mass-range M M largely unpop…
