The role of Wigner rotation in estimating the specific angular momentum of a Kerr spacetime
F. J. Lobo, M. Rivera-Tapia, G. Rubilar +1
We study the rotation of the polarization due to the gravitational field in the Kerr spacetime and the possibility of estimating the specific angular momentum that parameterizes th…

Discrimination of metric theories
F. J. Lobo, M. Rivera-Tapia, G. Rubilar +2
We study the possibility of discriminating between metric theories within the Parametrized Post-Newtonian formalism. In this approach, the two-dimensional quantum state of a massiv…

Neutron stars in 4D Einstein-Gauss-Bonnet gravity
Alejandro Saavedra, Octavio Fierro, Michael Gammon +2
Since the derivation of a well-defined limit for 4D Einstein-Gauss-Bonnet (4DEGB) gravity coupled to a scalar field, there has been considerable interest in testing it as a…
