The Emergence of Gravitational Wave Science: 100 Years of Development of Mathematical Theory, Detectors, Numerical Algorithms, and Data Analysis Tools
Michael Holst, Olivier Sarbach, Manuel Tiglio +1
On September 14, 2015, the newly upgraded Laser Interferometer Gravitational-wave Observatory (LIGO) recorded a loud gravitational-wave (GW) signal, emitted a billion light-years a…
Continuum and Discrete Initial-Boundary-Value Problems and Einstein's Field Equations
Olivier Sarbach, Manuel Tiglio
Many evolution problems in physics are described by partial differential equations on an infinite domain; therefore, one is interested in the solutions to such problems for a given…
Numerical simulations with a first order BSSN formulation of Einstein's field equations
J. David Brown, Peter Diener, Scott E. Field +7
We present a new fully first order strongly hyperbolic representation of the BSSN formulation of Einstein's equations with optional constraint damping terms. We describe the charac…
Turduckening black holes: an analytical and computational study
David Brown, Peter Diener, Olivier Sarbach +2
We provide a detailed analysis of several aspects of the turduckening technique for evolving black holes. At the analytical level we study the constraint propagation for a general…
Excision without excision: the relativistic turducken
David Brown, Olivier Sarbach, Erik Schnetter +4
to turducken (turduckens, turduckening, turduckened, turduckened) [math.]: To stuff a black hole. We analyze and apply an alternative to black hole excision based on smoothing the…
Recent analytical and numerical techniques applied to the Einstein equations
Dave Neilsen, Luis Lehner, Olivier Sarbach +1
Combining deeper insight of Einstein's equations with sophisticated numerical techniques promises the ability to construct accurate numerical implementations of these equations. We…
