Numerical Relativity reaching into the land of Post-NewtonianTheory

ORAL

Abstract

Extensive code improvement of the Spectral Einstein Code has made it now possible for us to perform simulations that start at frequencies where Post Newtonian Theory is accurate. As a first such run we have performed a 175 orbit, mass-ratio 7, non-spinning BBH run at several resolutions. Runs of this type open the gate towards a new level of testing of the various BBH waveform approximants. The important question of ``how long should runs be'' receives a new meaning. The talk will focus on current status as well as future plans for these ultra-long simulations.
