Periodic Analogs of Multiple Black Holes Solutions
Omar E. Ortiz, Javier Peraza
In this article, we extend the numerical studies developed in [arXiv:2210.12898] to construct periodic stationary axisymmetric solutions containing multiple horizons in each fundam…
Periodic analogues of the Kerr solutions: a numerical study
Javier Peraza, Martín Reiris, Omar E. Ortiz
In recent years black hole configurations with non standard topology or with non-standard asymptotic have gained considerable attention. In this article we carry out numerical inve…
Size, angular momentum and mass for objects
Pablo Anglada, M. E. Gabach-Clement, Omar E. Ortiz
We obtain a geometrical inequality involving the ADM mass, the angular momentum and the size of an ordinary, axially symmetric object. We use the monotonicity of the Geroch quasi-l…
The inequality between size and charge in spherical symmetry
Pablo Anglada, Sergio Dain, Omar E. Ortiz
We prove that for a spherically symmetric charged body two times the radius is always strictly greater than the charge of the body. We also prove that this inequality is sharp. Fin…
On well-posedness, linear perturbations and mass conservation for axisymmetric Einstein equation
Sergio Dain, Omar E. Ortiz
For axially symmetric solutions of Einstein equations there exists a gauge which has the remarkable property that the total mass can be written as a conserved, positive definite, i…
Numerical evidences for the angular momentum-mass inequality for multiple axially symmetric black holes
Sergio Dain, Omar Ortiz
We present numerical evidences for the validity of the inequality between the total mass and the total angular momentum for multiple axially symmetric (non-stationary) black holes.…
