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…
LISA and the LISA Science Team
Anna Heffernan, Chiara Caprini, Neil Cornish +19
LISA, the Laser Interferometer Space Antenna, due to launch mid-2035, is a large class space mission by the European Space Agency (ESA). In partnership with NASA and ESA-member sta…
A new sample of Little Red Dots at in DESI DR1: Broad Balmer lines, low ionization spectrum and no variability
Kevin Park, Alberto Torralba, Jorryt Matthee +4
JWST has unveiled an abundant population of compact broad-line emitters largely at , the Little Red Dots (LRDs), which might represent a previously unprobed supermassive…
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…
