Accretion onto a Supermassive Black Hole Binary Before Merger
Mark J. Avara, Julian H. Krolik, Manuela Campanelli +3
While supermassive binary black holes inspiral toward merger they may also experience significant accretion of matter from a surrounding disk. We study the dynamics of this system,…
Mini-disk accretion onto spinning black hole binaries: quasi-periodicities and outflows
Luciano Combi, Federico G. Lopez Armengol, Manuela Campanelli +4
We perform a full 3D general relativistic magnetohydrodynamical (GRMHD) simulation of an equal-mass, spinning, binary black hole approaching merger, surrounded by a circumbinary di…
Circumbinary Disk Accretion into Spinning Black Hole Binaries
Federico G. Lopez Armengol, Luciano Combi, Manuela Campanelli +6
Supermassive black hole binaries are likely to accrete interstellar gas through a circumbinary disk. Shortly before merger, the inner portions of this circumbinary disk are subject…
Quasi-Periodicity of Supermassive Binary Black Hole Accretion Approaching Merger
Dennis B. Bowen, Vassilios Mewes, Scott C. Noble +3
In this paper we continue the first ever study of magnetized mini-disks coupled to circumbinary accretion in a supermassive binary black hole (SMBBH) approaching merger reported in…
Electromagnetic Emission from Supermassive Binary Black Holes Approaching Merger
Stéphane d'Ascoli, Scott C. Noble, Dennis B. Bowen +3
We present the first fully relativistic prediction of the electromagnetic emission from the surrounding gas of a supermassive binary black hole system approaching merger. Using a r…
Quasi-Periodic Behavior of Mini-Disks in Binary Black Holes Approaching Merger
Dennis B. Bowen, Vassilios Mewes, Manuela Campanelli +3
We present the first magnetohydrodynamic simulation in which a circumbinary disk around a relativistic binary black hole feeds mass to individual accretion disks ("mini-disks") aro…
Relativistic Dynamics and Mass Exchange in Binary Black Hole Mini-Disks
Dennis B. Bowen, Manuela Campanelli, Julian H. Krolik +2
We present the first exploration of relativistic gas dynamics in the immediate vicinity of binary black holes as the system inspirals close to merger in the gravitational radiation…
