Blueshift of light rays induced by gravitational wave memory effect
F. L. Carneiro, S. C. Ulhoa, J. W. Maluf
The article deals with photon propagation in pp-wave spacetimes in the strong gravitational-wave regime and its consequences for redshift measurements. We show that null geodesics…
Perturbations of the Gravitational Energy in the TEGR: Quasinormal Modes of the Schwarzschild Black Hole
J. W. Maluf, S. C. Ulhoa, F. L. Carneiro +1
We calculate the gravitational energy spectrum of the perturbations of a Schwarzschild black hole described by quasinormal modes, in the framework of the teleparallel equivalent of…
Non-linear Plane Gravitational Waves as Space-time Defects
F. L. Carneiro, S. C. Ulhoa, J. W. Maluf +1
We consider non-linear plane gravitational waves as propagating space-time defects, and construct the Burgers vector of the waves. In the context of classical continuum systems, th…
On the Quantization of Burgers Vector and Gravitational Energy in the Space-Time of a Conical Defect
F. L. Carneiro, S. C. Ulhoa, J. F. da Rocha-Neto +1
A conical topological defect is the result of translational and/or rotational deformations of spacetime, in particular the Burgers vector describes the translational deformation. S…
Energy-momentum and angular-momentum of a gyratonic pp-waves spacetime
F. L. Carneiro, S. C. Ulhoa, J. F. da Rocha-Neto
Gyratonic plane fronted gravitational waves are exact solutions of Einstein's field equations, which correspond to gravitational waves that carry momentum and angular-momentum. Usi…
Difficulties of Teleparallel Theories of Gravity with Local Lorentz Symmetry
J. W. Maluf, S. C. Ulhoa, J. F. da Rocha-Neto +1
A brief discussion is made about the relevance of surface terms in the Lagrangian and Hamiltonian formulations of theories of gravity. These surface terms play an important role in…
