Gravitational waves, black holes and cosmic strings in cylindrical symmetry
The emission of gravitational waves by black holes is under intense investigation, in preparation for the expected observational study of black holes and other astrophysical objects by upcoming gravitational-wave detectors. Most of this work is either numerical or in an approximation, since we lack a full physical understanding of the dynamics of black holes and gravitational waves. The accepte...
متن کاملExtraction of gravitational waves in numerical relativity
A numerical-relativity calculation yields in general a solution of the Einstein equations including also a radiative part, which is in practice computed in a region of finite extent. Since gravitational radiation is properly defined only at null infinity and in an appropriate coordinate system, the accurate estimation of the emitted gravitational waves represents an old and non-trivial problem ...

متن کاملNonlinear Gravitational Waves: Their Form and Effects
Similarly to a Yang–Mills propagating field, which must be nonlinear if it is to transport its own charge, only a nonlinear gravitational wave is able to transport energy and momentum. The second order solution describing such physical waves is obtained. The effects they produce on free particles consist of nonlinear oscillations along the direction of propagation. This is the signature a detec...
متن کاملCanonical Quantization of Cylindrical Gravitational Waves with Two Polarizations
The canonical quantization of the essentially nonlinear midisuperspace model describing cylindrically symmetric gravitational waves with two polarizations is presented. A Fock space type representation is constructed. It is based on a complete set of quantum observables. Physical expectation values may be calculated in arbitrary excitations of the vacuum. Our approach provides a non-linear gene...
