Mode coupling in the nonlinear response of black holes
Yosef Zlochower, Roberto Gomez, Sascha Husa +2
We study the properties of the outgoing gravitational wave produced when a non-spinning black hole is excited by an ingoing gravitational wave. Simulations using a numerical code f…
Toward standard testbeds for numerical relativity
Miguel Alcubierre, Gabrielle Allen, Carles Bona +18
In recent years, many different numerical evolution schemes for Einstein's equations have been proposed to address stability and accuracy problems that have plagued the numerical r…
Computer Algebra Applications for Numerical Relativity
Sascha Husa, Christiane Lechner
We discuss the application of computer algebra to problems commonly arising in numerical relativity, such as the derivation of 3+1-splits, manipulation of evolution equations and a…
A numerical relativistic model of a massive particle in orbit near a Schwarzschild black hole
Nigel T. Bishop, Roberto Gomez, Sascha Husa +2
We present a method for computing the evolution of a spacetime containing a massive particle and a black hole. The essential idea is that the gravitational field is evolved using f…
