A Black Hole Kicked at Birth: MAXI J1305-704
The Astrophysical Journal Letters, 2023 When a compact object is formed in a binary, any mass lost during core collapse will impart a kick on the binary’s center of mass. Asymmetries in this mass loss or neutrino emission would impart an additional natal kick on the remnant black hole or ...

Black hole/pulsar binaries in the Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2018 ABSTRACT We have performed population synthesis calculation on the formation of binaries containing a black hole (BH) and a neutron star (NS) in the Galactic disc. Some of important input parameters, especially for the treatment of common envelope evolution, are updated in the calculation.

Silence of Binary Kerr Black Holes [PDF]
Physical Review Letters, 2020 A nontrivial S matrix generally implies a production of entanglement: starting with an incoming pure state, the scattering generally returns an outgoing state with nonvanishing entanglement entropy. It is then interesting to ask if there exists a nontrivial S matrix that generates no entanglement.

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.

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

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.

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.

A near horizon extreme binary black hole geometry
European Physical Journal C: Particles and Fields, 2019 A new solution of four-dimensional vacuum General Relativity is presented. It describes the near horizon region of the extreme (maximally spinning) binary black hole system with two identical extreme Kerr black holes held in equilibrium by a massless ...

Inventory of black hole binaries [PDF]
Symposium - International Astronomical Union, 2003 A small group of X-ray binaries currently provides the best evidence for the existence of stellar-mass black holes. These objects are interacting binary systems where the X-rays arise from accretion of material onto a compact object (i.e., an object with a radius of less than a few hundred km). In some favourable cases, optical studies of the companion

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.
