The irreducible mass of a regular rotating black hole
F. L. Carneiro, S. C. Ulhoa, J. F. da Rocha-Neto +1
This article presents an analysis of regular rotating black hole solutions within the framework of Teleparallel Equivalent to General Relativity (TEGR). The study evaluates the tot…
Energy of Gravitational Radiation and the Background Energy of the Space-Time
J. W. Maluf, F. Lessa Carneiro, S. C. Ulhoa +1
We address the issue of gravitational radiation in the context of the Bondi-Sachs space-time, and consider the expression for the gravitational energy of the radiation obtained in…
Tetrad Fields, Reference Frames, and the Gravitational Energy-Momentum in the Teleparallel Equivalent of General Relativity
J. W. Maluf, F. L. Carneiro, S. C. Ulhoa +1
We review the concept and definitions of the energy-momentum and angular momentum of the gravitational field in the teleparallel equivalent of general relativity (TEGR). The import…
Kerr-Schild Tetrads and the Nijenhuis Tensor
J. W. Maluf, F. L. Carneiro, S. C. Ulhoa +1
We write the Kerr-Schild tetrads in terms of the flat space-time tetrads and of a (1,1) tensor . This tensor can be considered as a projection operator, since it transforms…
On the total energy conservation of the Alcubierre spacetime
F. L. Carneiro, S. C. Ulhoa, J. W. Maluf +1
In this article, we consider the Alcubierre spacetime, such a spacetime describes a ``bubble'' that propagates with arbitrary global velocity. This setting allows movement at a spe…
Gravitational Pressure, apparent horizon and thermodynamics of FLRW universe in the teleparallel gravity
J. F. da Rocha-Neto, B. R. Morais
In the context of the teleparallel equivalent of general relativity the concept of gravitational pressure and gravitational energy-momentum arisen in a natural way. In the case of…
