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…
