@article{Zhang2013JointAF, title={Joint approach for reducing eccentricity and spurious gravitational radiation in binary black hole initial data construction}, author={Fan Zhang and B'ela Szil'agyi}, journal={Physical Review D}, year={2013}, volume={88}, pages={084033} }

At the beginning of binary black hole simulations, there is a pulse of spurious radiation (or junk radiation) resulting from the initial data not matching astrophysical quasi-equilibrium inspiral exactly. One traditionally waits for the junk radiation to exit the computational domain before taking physical readings, at the expense of throwing away a segment of the evolution, and with the hope that junk radiation exits cleanly. We argue that this hope does not necessarily pan out, as junk… Expand
