A Galerkin-Collocation domain decomposition method: application to the evolution of cylindrical gravitational waves
W. O. Barreto, J. A. Crespo, H. P. de Oliveira +1
We present a Galerkin-Collocation domain decomposition algorithm applied to the evolution of cylindrical unpolarized gravitational waves. We show the effectiveness of the algorithm…
Nonlinear interaction between electromagnetic and gravitational waves: an appraisal
W. Barreto, H. P. de Oliveira, E. L. Rodrigues
Wave propagation of field disturbances is ubiquitous. The electromagnetic and gravitational are cousin theories in which the corresponding waves play a relevant role to understand…
Mass gap in the critical gravitational collapse of a kink
W. Barreto, J. Crespo, H. de Oliveira +2
We study the gravitational collapse of a kink within spherical symmetry and the characteristic formulation of General Relativity. We explore some expected but elusive gravitational…
Nonlinear evolution of cylindrical gravitational waves: numerical method and physical aspects
Juliana Celestino, H. P. de Oliveira, E. L. Rodrigues
General cylindrical waves are the simplest axisymmetrical gravitational waves that contain both and modes of polarization. In this paper, we have studied the evolution…
Three dimensional distorted black holes: using the Galerkin-Collocation method
H. P. de Oliveira, E. L. Rodrigues
We present an implementation of the Galerkin-Collocation method to determine the initial data for non-rotating distorted three dimensional black holes in the inversion and puncture…
A Kolmogorov-Zakharov Spectrum in Gravitational Collapse
H. P. de Oliveira, Leopoldo A. Pando Zayas, E. L. Rodrigues
We study black hole formation during the gravitational collapse of a massless scalar field in asymptotically spacetimes for . We conclude that spherically symmetric…
