The motion of a Schwarzschild black hole with velocity v{sub 0}={beta}{sub 0}c through a constant magnetic field B{sub 0} in vacuum induces a component of the electric field along the magnetic field, generating a nonzero second Poincare electromagnetic invariant {sup *}F{center_dot}F{ne}0. This will produce (e.g., via radiative effects and vacuum breakdown) an electric charge density of the order of {rho}{sub ind}=B{sub 0{beta}0}/(2{pi}eR{sub G}), where R{sub G}=2GM/c{sup 2} is the…

Slowly balding black holes
The 'no-hair' theorem, a key result in general relativity, states that an isolated black hole is defined by only three parameters: mass, angular momentum, and electric charge; this asymptotic state
Astrophysical jets from boosted compact objects
We perform full 3D numerical simulations of compact objects, such as black holes or neutron stars, boosted through an ambient forcefree plasma that posses a uniform magnetization. We study jet
Mergers of Charged Black Holes: Gravitational Wave Events, Short Gamma-Ray Bursts, and Fast Radio Bursts
The discoveries of GW 150914, GW 151226, and LVT 151012 suggest that double black hole (BH-BH) mergers are common in the universe. If at least one of the two merging black holes carries certain
Electromagnetic power of merging and collapsing compact objects
TLDR
It is argued that the collapse of a NS into the BH happens smoothly, without natural formation of current sheets or other dissipative structures on the open field lines and, thus, does not allow the magnetic field to become disconnected from the star and escape to infinity.
Charging and Electromagnetic Radiation during the Inspiral of a Black Hole–Neutron Star Binary
Because mergers of black hole–neutron star (BH–NS) binaries are widely argued to produce both gravitational and electromagnetic waves, these binaries are among the most attractive systems in the era
Big black hole, little neutron star: Magnetic dipole fields in the Rindler spacetime
As a black hole and neutron star approach during inspiral, the field lines of a magnetized neutron star eventually thread the black hole event horizon and a short-lived electromagnetic circuit is
Boosted Kerr black holes in general relativity
A solution of Einstein's vacuum field equation is derived that describes a general boosted Kerr black hole relative to a Lorentz frame at future null infinity. The metric contains five independent
Influence of frame-dragging on magnetic null points near rotating black holes
Understanding the mechanisms of particle acceleration from the vicinity of black holes poses a challenge. Electromagnetic effects are thought to be a prime suspect, but details still need an
Blindly detecting orbital modulations of jets from merging supermassive black holes
In the last few years before merger, supermassive black hole binaries will rapidly inspiral and precess in a magnetic field imposed by a surrounding circumbinary disk. Multiple simulations suggest
Analytic properties of the electromagnetic field of binary compact stars and electromagnetic precursors to gravitational waves
We analytically study the properties of the electromagnetic field in vacuum around close binary compact stars containing at least one neutron star. We show that the orbital motion of the neutron star
