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…
Superposed metric for spinning black hole binaries approaching merger
Luciano Combi, Federico G. Lopez Armengol, Manuela Campanelli +4
We construct an approximate metric that represents the spacetime of spinning binary black holes (BBH) approaching merger. We build the metric as an analytical superposition of two…
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…
PatchworkWave: A Multipatch Infrastructure for Multiphysics/Multiscale/Multiframe/Multimethod Simulations at Arbitrary Order
Dennis B. Bowen, Mark Avara, Vassilios Mewes +6
We present an extension of the PatchworkMHD code [1], itself an MHD-capable extension of the Patchwork code [2], for which several algorithms presented here were co-developed. Its…
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…
