Rio: A new computational framework for accurate initial data of binary black holes
W. Barreto, P. C. M. Clemente, H. P. de Oliveira +1
We present a computational framework (Rio) in the ADM 3+1 approach for numerical relativity. This work enables us to carry out high resolution calculations for initial data of two…
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…
Fixed mesh refinement in the characteristic formulation of General Relativity
W. Barreto, H. P. de Oliveira, B. Rodriguez-Mueller
We implement a spatially fixed mesh refinement under spherical symmetry for the characteristic formulation of General Relativity. The Courant-Friedrich-Levy (CFL) condition lets us…
A (gravitational) toy story
W. Barreto, H. P. de Oliveira, B. Rodriguez-Mueller
Frequently in Physics, insights and conclusions can be drawn from simple, idealized models. The discovery of critical behavior in the gravitational collapse of a massless scalar fi…
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…
Heat flow in the postquasistatic approximation
B. Rodríguez-Mueller, C. Peralta, W. Barreto +1
We apply the postquasistatic approximation to study the evolution of spherically symmetric fluid distributions undergoing dissipation in the form of radial heat flow. For a model w…
