Evolution of Binary Black Hole Spacetimes [PDF]
Physical Review Letters, 2005 We describe early success in the evolution of binary black hole spacetimes with a numerical code based on a generalization of harmonic coordinates. Indications are that with sufficient resolution this scheme is capable of evolving binary systems for ...

Massive Black Hole Binary Evolution [PDF]
Living Reviews in Relativity, 2005 Coalescence of binary supermassive black holes (SBHs) would constitute the strongest sources of gravitational waves to be observed by LISA. While the formation of binary SBHs during galaxy mergers is almost inevitable, coalescence requires that the ...

Meet the Parents: The Progenitor Binary for the Supermassive Black Hole Candidate in E1821+643
The Astrophysical Journal Letters, 2023 The remnants of binary black hole mergers can be given recoil kick velocities up to 5000 km s ^−1 due to anisotropic emission of gravitational waves. E1821+643 is a recoiling supermassive black hole candidate with spectroscopically offset, broad emission

Coalescence of Kerr Black Holes—Binary Systems from GW150914 to GW170814
Entropy, 2019 We investigate the energy of the gravitational wave from a binary black hole merger by the coalescence of two Kerr black holes with an orbital angular momentum.

Foundations of multiple black hole evolutions [PDF]
, 2008 We present techniques for long-term, stable, and accurate evolutions of multiple-black-hole spacetimes using the `moving puncture' approach with fourth- and eighth-order finite difference stencils.

Black Hole Binary Mergers [PDF]
Highlights of Astronomy, 2005 AbstractI overview the current understanding of the evolution of massive black hole (MBH) binaries in the center of the host stellar system. One of the main questions is whether the stellar dynamical effect can make the MBH binary hard enough that they can merge through gravitational wave radiation.

Binary black hole in a double magnetic monopole field
European Physical Journal C: Particles and Fields, 2018 Ambient magnetic fields are thought to play a critical role in black hole jet formation. Furthermore, dual electromagnetic signals could be produced during the inspiral and merger of binary black hole systems.

Inferences about supernova physics from gravitational-wave measurements: GW151226 spin misalignment as an indicator of strong black-hole natal kicks [PDF]
, 2017 The inferred parameters of the binary black hole GW151226 are consistent with nonzero spin for the most massive black hole, misaligned from the binary's orbital angular momentum.

Black hole binary dynamics [PDF]
Astrophysics and Space Science, 2003 We discuss a new N-body simulation method for studying black hole binary dynamics. This method avoids previous numerical problems due to large mass ratios and trapped orbits with short periods. A treatment of relativistic effects is included when the associated time-scale becomes small.
