Recoil-regulated extreme mass-ratio inspirals in AGN disks
LingQin Xue, Zoltán Haiman, Hiromichi Tagawa +1
Extreme mass-ratio inspirals (EMRIs) are among the primary targets of future space-based gravitational-wave observatories, such as LISA, TianQin, and Taiji. Active galactic nucleus…
High-Spin BBH Subpopulation from AGN Accretion
I. Bartos, Z. Haiman
The formation environments of merging binary black holes remain uncertain. While hierarchical assembly in dense stellar clusters has been widely explored as an explanation for blac…
Properties of black hole mergers in disks of active galactic nuclei
Hiromichi Tagawa, Zoltán Haiman, Bence Kocsis
Ground-based gravitational wave (GW) observatories have detected approximately 200 binary black hole (BH) mergers. The astrophysical origin of these events are debated, with eviden…
Electromagnetic Flares from Compact-Object Mergers in AGN Disks: Signatures and Predictions
Hiromichi Tagawa, Zoltán Haiman, Shigeo S. Kimura +2
Accretion disks in active galactic nuclei (AGN) are promising sites for mergers of stellar-mass black holes (BHs) detectable via gravitational waves (GWs). These environments facil…
Self-lensing flares from black hole binaries V: systematic searches in LSST
Kevin Park, Zoltan Haiman, Chengcheng Xin +3
The Vera C. Rubin Observatory has now seen first light, and over a 10 year duration, LSST is projected to catalogue tens of millions of quasars, many of which are expected to be as…
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…
Triples as Links between Binary Black Hole Mergers, their Electromagnetic Counterparts, and Galactic Black Holes
Smadar Naoz, Zoltan Haiman, Eliot Quataert +1
We propose a formation pathway linking black holes (BHs) observed in gravitational-wave (GW) mergers, wide BH-stellar systems uncovered by Gaia, and accreting low-mass X-ray binari…
Accretion is All You Need: Black Hole Spin Alignment in Merger GW231123 Indicates Accretion Pathway
Imre Bartos, Zoltan Haiman
GW231123 represents the most massive binary-black-hole merger detected to date, lying firmly within, or even above, the pair-instability mass gap. The component spins are both exce…
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…
Thermal X-ray signatures in late-stage unequal-mass massive black hole binary mergers
Luke Major Krauth, Jordy Davelaar, Zoltán Haiman +3
The multi-messenger combination of gravitational waves (GWs) from merging massive black hole binaries (MBHBs) and the electromagnetic (EM) counterpart from the surrounding circumbi…
Self-lensing flares from black hole binaries IV: the number of detectable shadows
Kevin Park, Chengcheng Xin, Jordy Davelaar +1
Sub-parsec supermassive black hole (SMBH) binaries are expected to be common in active galactic nuclei (AGN), as a result of the hierarchical build-up of galaxies via mergers. Whil…
Time-dependent models of AGN disks with radiation from embedded stellar-mass black holes
Marguerite Epstein-Martin, Hiromichi Tagawa, Zoltan Haiman +1
The brightest steady sources of radiation in the universe, active galactic nuclei (AGN), are powered by gas accretion onto a central supermassive black hole (SMBH). The large sizes…
Shock cooling and breakout emission for optical flares associated with gravitational wave events
Hiromichi Tagawa, Shigeo S. Kimura, Zoltán Haiman +2
The astrophysical origin of stellar-mass black hole (BH) mergers discovered through gravitational waves (GWs) is widely debated. Mergers in the disks of active galactic nuclei (AGN…
Black Hole Binaries in AGN Accretion Discs II: Gas Effects on Black Hole Satellite Scatterings
Connar Rowan, Henry Whitehead, Tjarda Boekholt +2
The black hole (BH) binaries in active galactic nuclei (AGN) are expected to form mainly through scattering encounters in the ambient gaseous medium. Recent simulations, including…
Cosmic Evolution of Stellar-mass Black Hole Merger Rate in Active Galactic Nuclei
Y. Yang, I. Bartos, Z. Haiman +3
Binary black hole mergers encode information about their environment and the astrophysical processes that led to their formation. Measuring the redshift dependence of their merger…
GW170817A as a Hierarchical Black Hole Merger
V. Gayathri, I. Bartos, Z. Haiman +4
Despite the rapidly growing number of stellar-mass binary black hole mergers discovered through gravitational waves, the origin of these binaries is still not known. In galactic ce…
Hierarchical Black Hole Mergers in Active Galactic Nuclei
Yang Yang, Imre Bartos, V. Gayathri +8
The origins of the stellar-mass black hole mergers discovered by LIGO/Virgo are still unknown. Here we show that, if migration traps develop in the \add{accretion} disks of Active…
On stellar-mass black hole mergers in AGN disks detectable with LIGO

B. McKernan, K. E. S. Ford, B. Kocsis +1
(abridged) When a sufficiently massive satellite (or secondary) black hole is embedded in a gas disk around a (primary) supermassive black hole, it can open an empty gap in the dis…
