Lower tensor-to-scalar ratio as possible signature of modified gravity

Abraão J. S. Capistrano, Rafael C. Nunes, Luís A. Cabral

This paper simplifies the induced four-dimensional gravitational equations originating from a five-dimensional bulk within the framework of Nash's embeddings, incorporating them 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 Black Hole Acceleration in the C-metric Space-time

F. L. Carneiro, S. C. Ulhoa, J. W. Maluf

We consider the C-metric as a gravitational field configuration that describes an accelerating black hole in the presence of a semi-infinite cosmic string, along the accelerating d…
