On the Gravitational Energy of Axial Perturbations in Regular Black Holes
S. C. Ulhoa, F. L. Carneiro, B. C. C. Carneiro
The article deals with the gravitational energy associated with axial perturbations of regular black holes. We review the stability of the geometry under odd-parity perturbations a…
On the Gravitational Angular Momentum of Axial Perturbations of a Regular Black Hole
S. C. Ulhoa, F. L. Carneiro, B. C. C. Carneiro
This Letter deals with the gravitational angular momentum carried by axial (odd-parity) perturbations of the Bardeen regular black hole within the teleparallel equivalent of genera…
On a Gödel-like Solution in Non-Relativistic Gravity
A. F. Santos, R. G. G. Amorim, K. V. S. Araújo +1
The article deals with Gödel-like solutions in the context of Galilean gravity, a geometric formulation of non-relativistic gravitation defined on a five-dimensional Galilean mani…
On Nonrelativistic Isotropic and Homogeneous Universe
R. G. G. Amorim, A. F. Santos, K. V. S. Araújo +1
This article deals with a nonrelativistic cosmological model based on Galilean covariance, formulated within a five-dimensional Galilean manifold. Within this framework, we constru…
On Nanocones as a Gravitational Analog System
F. L. Carneiro, B. C. C. Carneiro, D. L. Azevedo +1
This study delves into the fundamental properties of graphene and boron nitride (BN) nanostructures, exploring their torsional energy characteristics within the framework of Telepa…
