Galerkin-Collocation domain decomposition method for arbitrary binary black holes
W. Barreto, P. C. M. Clemente, H. P. de Oliveira +1
We present a new computational framework for the Galerkin-collocation method for double domain in the context of ADM 3+1 approach in numerical relativity. This work enables us to p…
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…
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…
Numerical evolution of radiative Robinson-Trautman spacetimes
H. P. de Oliveira, E. L. Rodrigues
The evolution of spheroids of matter emitting gravitational waves and null radiation field is studied in the realm of radiative Robinson-Trautman spacetimes. The null radiation fie…
