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…

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…

Plato's view on supermassive black hole binaries: Exploring the faint limit of ESA's Plato space mission

Nicholas Jannsen, Pablo Huijse, Kevin Park +3

The search for supermassive black hole binaries (SMBHBs) has, in recent years, seen the dawn of exploration with several hundred candidates claimed from photometric and spectroscop…
