Evolving Metric Perturbations in dynamical Chern-Simons Gravity
Maria Okounkova, Mark A. Scheel, Saul A. Teukolsky
We present a well-posed constraint-preserving scheme for evolving first-order metric perturbations on an arbitrary background with arbitrary source. We use this scheme to evolve th…
A high-order, conservative integrator with local time-stepping
William Throwe, Saul A. Teukolsky
We present a family of multistep integrators based on the Adams-Bashforth methods. These schemes can be constructed for arbitrary convergence order with arbitrary step size variati…
Numerical black hole initial data and shadows in dynamical Chern-Simons gravity
Maria Okounkova, Mark A. Scheel, Saul A. Teukolsky
We present a scheme for generating first-order metric perturbation initial data for an arbitrary background and source. We then apply this scheme to derive metric perturbations in…
Constraining the parameters of GW150914 & GW170104 with numerical relativity surrogates
Prayush Kumar, Jonathan Blackman, Scott E. Field +7
Gravitational-wave detectors have begun to observe coalescences of heavy black holes at a consistent pace for the past few years. Accurate models of gravitational waveforms are ess…
General-relativistic neutron star evolutions with the discontinuous Galerkin method
François Hébert, Lawrence E. Kidder, Saul A. Teukolsky
Simulations of relativistic hydrodynamics often need both high accuracy and robust shock-handling properties. The discontinuous Galerkin method combines these features --- a high o…
Critical behavior in 3-d gravitational collapse of massless scalar fields
Nils Deppe, Lawrence E. Kidder, Mark A. Scheel +1
We present results from the first study of critical behavior in 3-d gravitational collapse. The source of the gravitational field is a massless scalar field. This is a well-studied…
