Collisions of oppositely charged black holes
Miguel Zilhão, Vitor Cardoso, Carlos Herdeiro +2
The first fully non-linear numerical simulations of colliding charged black holes in D=4 Einstein-Maxwell theory were recently reported arXiv:1205.1063. These collisions were perfo…
Dynamic Fisheye Grids for Binary Black Holes Simulations
Miguel Zilhão, Scott C. Noble
We present a new warped gridding scheme adapted to simulating gas dynamics in binary black hole spacetimes. The grid concentrates grid points in the vicinity of each black hole to…
An Introduction to the Einstein Toolkit
Miguel Zilhão, Frank Löffler
We give an introduction to the Einstein Toolkit, a mature, open-source computational infrastructure for numerical relativity based on the Cactus Framework, for the target group of…
New frontiers in Numerical Relativity
Miguel Zilhão
The first attempts at solving a binary black hole spacetime date back to the 1960s, with the pioneering works of Hahn and Lindquist. In spite of all the computational advances and…
