Null dust in canonical gravity
Jiří Bičák,Karel V. Kuchař +1 more
TL;DR: In this article, the Lagrangian and Hamiltonian framework is extended to include null dust as a source into canonical gravity, and the Dirac constraint quantization of the system is formally accomplished by imposing the new constraints as quantum operator restrictions on state functionals.
Journal ArticleDOI
Evidence of cosmic strings by the observation of the alignment of quasar polarization axes on Mpc scale
TL;DR: In this paper, an emergent azimuthal-angle dependency of the Nielsen-Olesen vortices was found in the general relativistic situation just after the symmetry breaking at GUT-scale.
Journal ArticleDOI
Alignment of Quasar Polarizations on Large Scales Explained by Warped Cosmic Strings
TL;DR: In this paper, it was shown that the effective Einstein 4D equations on an axially symmetric spacetime, contain a back-reaction term on the righthand side caused by the projected 5D Weyl tensor and can act as a dark energy term.
Journal ArticleDOI
The generation of gravitational waves by the resonant interaction of sound waves
TL;DR: In this article, it was shown that the resonant interaction of sound waves is a source of gravitational waves in general relativity and derived an asymptotic equation that describes this process, and computed the interaction coefficient for the quadratically nonlinear coupling between sound waves and gravitational waves.
Journal ArticleDOI
Nonlinear Gravitational Waves as Dark Energy in Warped Spacetimes
TL;DR: In this paper, an azimuthal-angle dependent approximate wave-like solution to second order on a warped five-dimensional manifold with a self-gravitating U(1) scalar gauge field (cosmic string) on the brane using the multiple-scale method was found.

Construction de solutions radiatives approchées des équations d'Einstein
TL;DR: In this article, the Ricci tensor of the Vaydya metric (13.1) was shown to be bounded by an oscillatory perturbation, and the first and second derivatives of this metric were shown to satisfy the required conditions of boundedness.

The averaged Lagrangian and high-frequency gravitational waves
Malcolm MacCallum,A. H. Taub +1 more
TL;DR: The averaged Lagrangian technique of Whitham is applied to the second variation Lagrangians for the perturbations of a general-relativistic spacetime.
