Rotation of inertial frames by angular momentum of matter and waves
William Barker, Tomáš Ledvinka, Donald Lynden-Bell +1
We elucidate the dynamics of a thin spherical material shell with a tangential pressure, using a new approach. This is both simpler than the traditional method of extrinsic curvatu…
Kinematic restrictions on particle collisions near extremal black holes: A unified picture
Filip Hejda, Jiří Bičák
In 2009, Banados, Silk and West (BSW) pointed out the possibility of having an unbounded limit of centre-of-mass collision energy for test particles in the field of an extremal Ker…
Aspects of Stability of Hairy Black Holes
Andres Anabalon, Jiří Bičák
We analyze spherical and odd-parity linear perturbations of hairy black holes with a minimally coupled scalar field.
Hairy black holes: stability under odd-parity perturbations and existence of slowly rotating solutions
Andres Anabalon, Jiří Bičák, Joel Saavedra
We show that, independently of the scalar field potential and of specific asymptotic properties of the spacetime (asymptotically flat, de Sitter or anti-de Sitter), any static, sph…
On Fast Linear Gravitational Dragging
D. Lynden-Bell, J. Bičák, J. Katz
A new formula is given for the fast linear gravitational dragging of the inertial frame within a rapidly accelerated spherical shell of deep potential. The shell is charged and is…
The art of science: interview with Professor John Archibald Wheeler
Jiři Bičák
During the conference on the methods of differential geometry in physics in Warsaw in June 1976, Professor Wheeler gave an interview for the Czechoslovak Journal of Physics A. Afte…
Electromagnetic sources distributed on shells in a Schwarzschild background
N. Gürlebeck, J. Bičák, A. C. Gutiérrez-Piñeres
In the Introduction we briefly recall our previous results on stationary electromagnetic fields on black-hole backgrounds and the use of spin-weighted spherical harmonics. We then…
Axisymmetric electrovacuum spacetimes with an additional Killing vector and radiation
A. Pravdova, J. Bicak
Main results concerning allowable additional symmetries of axially symmetric electrovacuum spacetimes are summarized. These are translational Killing vectors and the boost Killing…
Exact radiative spacetimes: some recent developments
Jiri Bicak
Five classes of radiative solutions of Einstein's field equations are discussed in the light of some new developments. These are plane waves and their collisions, cylindrical waves…
Axisymmetric electrovacuum spacetimes with a translational Killing vector at null infinity
J. Bicak, A. Pravdova
By using the Bondi-Sachs-van der Burg formalism we analyze the asymptotic properties at null infinity of axisymmetric electrovacuum spacetimes with a translational Killing vector a…
Spinning C-metric: radiative spacetime with accelerating, rotating black holes
J. Bicak, V. Pravda
The spinning C-metric was discovered by Plebanski and Demianski as a generalization of the standard C-metric which is known to represent uniformly accelerated non-rotating black ho…
Gauge Invariant Hamiltonian Formalism for Spherically Symmetric Gravitating Shells
P. Hajicek, J. Bicak
The dynamics of a spherically symmetric thin shell with arbitrary rest mass and surface tension interacting with a central black hole is studied. A careful investigation of all cla…
