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 manif…

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 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…

Nonrelativistic Spinless Particle in Vicinity of Schwarzschild-like Black Hole

Ronni Amorim, Vinicius Rispoli, Sérgio Ulhoa +1

In this article we analyze the behavior of a non-relativistic spinless particle near the event horizon of a Schwarzschild-like black hole. In this way, the Schrödinger covariant eq…

On Thermodynamics of Kerr Black Hole

S. C. Ulhoa, A. F. Santos, E. P. Spaniol +1

The gravitational Stefan-Boltzmann law is considered for the Kerr black hole in the weak-field limit. The energy-momentum tensor predicted by Teleparallelism Equivalent to General…
