Probing the Binary Black Hole Merger Regime with Scalar Perturbations

, 2008
We present results obtained by scattering a scalar field off the curved background of a coalescing binary black hole system. A massless scalar field is evolved on a set of fixed backgrounds, each provided by a spatial hypersurface generated numerically ...
