Abstract |
We estimate the energy radiated in the head-on collision of two equal D-dimensional Aichelburg-Sexl shock waves by solving perturbatively, to first order, the Einstein equations in the future of the collision. After finding the wave forms, we extract the estimated radiated energy and unveil a remarkably simple pattern, given the complexity of the framework: the estimated fraction of radiated energy matches the analytic expression 1/2-1/D, within the numerical error (less than 0.1%). Both this fit and the apparent horizon bound converge to 1/2 as D goes to infinity. Refs: arXiv:1105.2298; arXiv:1203.5355 |
