Gravitational energy in stationary spacetimes
Joseph Katz, Donald Lynden-Bell, Jiri Bicak
Static observers remain on Killing-vector world lines and measure the rest-mass+kinetic energies of particles moving past them, and the flux of that mechanical energy through space…
Black holes and magnetic fields
J. Bicak, V. Karas, T. Ledvinka
Stationary axisymmetric magnetic fields are expelled from outer horizons of black holes as they become extremal. Extreme black holes exhibit Meissner effect also within exact Einst…
Einstein equations: exact solutions
Jiri Bicak
In Einstein's general relativity, with its nonlinear field equations, the discoveries and analyzes of various specific explicit solutions made a great impact on understanding many…
Ultrarelativistic sources in nonlinear electrodynamics
Jiri Bicak, David Kubiznak
The fields of rapidly moving sources are studied within nonlinear electrodynamics by boosting the fields of sources at rest. As a consequence of the ultrarelativistic limit the del…
Fields of accelerated sources: Born in de Sitter
Jiri Bicak, Pavel Krtous
This paper deals thoroughly with the scalar and electromagnetic fields of uniformly accelerated charges in de Sitter spacetime. It gives details and makes various extensions of our…
