Boosted Kerr-Newman Black Holes
Rafael F. Aranha, Rodrigo Maier
In this paper we obtain a new solution of Einstein field equations which describes a boosted Kerr-Newman black hole relative to a Lorentz frame at future null infinity. To simplify…
General Boosted Kerr Black Holes and Papapetrou Electrodynamics
Rafael F. Aranha, Carlos E. Cedeño M., Rodrigo Maier +1
In this paper the spacetime of a general boosted Kerr black hole relative to a Lorentz frame at future null infinity is regarded as a background to examine its respective Papapetro…
New numerical framework for the generalized Baumgarte-Shapiro-Shibata-Nakamura formulation: The vacuum case for spherical symmetry
M. A. Alcoforado, R. F. Aranha, W. O. Barreto +1
Here we report a developed high performance and simplified version of the code denominated RIO, which can be easily extended, for the generalized BSSN formulation. We implement a c…
Maxwell Fields in Boosted Kerr Black Holes
Rafael F. Aranha, Carlos E. Cedeño M., Rodrigo Maier +1
The spacetime of a boosted Bondi-Sachs rotating black hole is considered as a proper background to examine electromagnetic configurations connected to analytic solutions of Maxwell…
Gravitational wave recoils in non-axisymmetric Robinson-Trautman spacetimes
R. F. Aranha, I. Damião Soares, E. V. Tonini
We examine the gravitational wave recoil waves and the associated net kick velocities in non-axisymmetric Robinson-Trautman spacetimes. We use characteristic initial data for the d…
Gravitational wave momentum extraction in non-axisymmetric Robinson-Trautman spacetimes
R. F. Aranha, I. Damião Soares, E. V. Tonini
We examine numerically the gravitational wave recoil in non-axisymmetric Robinson-Trautman spacetimes. We construct characteristic initial data for the Robinson-Trautman dynamics w…
