Gauge and radiation conditions in numerical relativity.
Abstract
Gauge conditions suitable for numerical calculations of emission of gravitational radiation by compact sources are explored, with particular emphasis on algebraic conditions which simplify the structure of the Einstein equations. The expansion of the radiation field in powers of r-1 is compared in different gauges, and formulas for outgoing wave boundary conditions and asymptotic energy flux in the waves are obtained in the radial gauge which are accurate through order r-2.
