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…
Computational General Relativistic Force-Free Electrodynamics: II. Characterization of Numerical Diffusivity
J. F. Mahlmann, M. A. Aloy, V. Mewes +1
Scientific codes are an indispensable link between theory and experiment; in (astro-)plasma physics, such numerical tools are one window into the universe's most extreme flows of e…
Computational General Relativistic Force-Free Electrodynamics: I. Multi-Coordinate Implementation and Testing
J. F. Mahlmann, M. A. Aloy, V. Mewes +1
General relativistic force-free electrodynamics is one possible plasma-limit employed to analyze energetic outflows in which strong magnetic fields are dominant over all inertial p…
Numerical relativity in spherical coordinates: A new dynamical spacetime and general relativistic MHD evolution framework for the Einstein Toolkit
Vassilios Mewes, Yosef Zlochower, Manuela Campanelli +4
We present SphericalNR, a new framework for the publicly available Einstein Toolkit that numerically solves the Einstein field equations coupled to the equations of general relativ…
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…
