Spectral Cauchy Characteristic Extraction of strain, news and gravitational radiation flux
Casey J. Handmer, Béla Szilágyi, Jeffrey Winicour
We present a new approach for the Cauchy-characteristic extraction of gravitational radiation strain, news function, and the flux of the energy-momentum, supermomentum and angular…
Gauge Invariant Spectral Cauchy Characteristic Extraction
Casey J. Handmer, Béla Szilágyi, Jeffrey Winicour
We present gauge invariant spectral Cauchy characteristic extraction. We compare gravitational waveforms extracted from a head-on black hole merger simulated in two different gauge…
Spectral Characteristic Evolution: A New Algorithm for Gravitational Wave Propagation
Casey J. Handmer, Béla Szilágyi
We present a spectral algorithm for solving the full nonlinear vacuum Einstein field equations in the Bondi framework. Developed within the Spectral Einstein Code (SpEC), we demons…
