Accurate initial data for Cauchy-characteristic evolution
Accurate gravitational-wave (GW) templates from numerical-relativity (NR) simulations are essential for GW science. These templates are typically computed at finite radii and extrapolated to future null infinity $\mathscr{I}^{+}$, the asymptotic boundary of spacetime. However, this procedure is known to not accurately...
