Galactic nuclei are expected to harbor the densest population of stellar-mass black holes. A significant fraction (∼30%) of these black holes can reside in binaries. We examine the fate of the black hole binaries in active galactic nuclei, which get trapped in the inner region of the accretion disk around the central supermassive black hole. We show that binary black holes can migrate into and then rapidly merge within the disk well within a Salpeter time. The binaries may also accrete a significant amount of gas from the disk, well above the Eddington rate. This could lead to detectable X-ray or gamma-ray emission, but would require hyper-Eddington accretion with a few percent radiative efficiency, comparable to thin disks. We discuss implications for gravitational wave observations and black hole population studies. We estimate that Advanced LIGO may detect ∼20 such, gas-induced binary mergers per year.","lang":"eng"}],"issue":"2","language":[{"iso":"eng"}],"date_published":"2017-01-27T00:00:00Z","article_type":"original","main_file_link":[{"url":" https://doi.org/10.48550/arXiv.1602.03831","open_access":"1"}],"status":"public","day":"27","user_id":"317138e5-6ab7-11ef-aa6d-ffef3953e345","date_created":"2024-09-06T08:51:48Z","author":[{"full_name":"Bartos, Imre","first_name":"Imre","last_name":"Bartos"},{"full_name":"Kocsis, Bence","first_name":"Bence","last_name":"Kocsis"},{"id":"7c006e8c-cc0d-11ee-8322-cb904ef76f36","last_name":"Haiman","full_name":"Haiman, Zoltán","first_name":"Zoltán"},{"full_name":"Márka, Szabolcs","first_name":"Szabolcs","last_name":"Márka"}],"date_updated":"2024-09-25T11:46:08Z","article_number":"165","oa_version":"Preprint","citation":{"ista":"Bartos I, Kocsis B, Haiman Z, Márka S. 2017.
