Abstract
En 中文
In Kelly et al (2007 Phys. Rev. D 76 024008), we presented new binary black-hole initial data adapted to puncture evolutions in numerical relativity. These data satisfy the constraint equations to 2.5 post-Newtonian order, and contain a transverse-traceless 'wavy' metric contribution, violating the standard assumption of conformal flatness. We report on progress in evolving these data with a modern moving puncture implementation of the BSSN equations in several numerical codes. We discuss the effect of the new metric terms on junk radiation and continuity of physical radiation extracted.
