Can stellar-mass black hole growth disrupt disks of active galactic nuclei? The role of mechanical feedback
Hiromichi Tagawa, Shigeo S. Kimura, Zoltán Haiman +3
Stellar-mass BHs (sBHs) are predicted to be embedded in active galactic nuclei (AGN) disks due to gravitational drag and in-situ star formation. However, we find that due to a high…
Micro Tidal Disruption Events in Active Galactic Nuclei
Y. Yang, I. Bartos, G. Fragione +5
Active galactic nuclei (AGNs) can act as black hole assembly lines, funneling some of the stellar-mass black holes from the vicinity of the galactic center into the inner plane of…
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…
