Detectable time delays from gravity waves?

Abstract

When a source of gravity waves is conveniently placed between the Earth and some source of electromagnetic waves, preferably a pulsating source, the magnitude of time delays induced by the gravity waves, in optimal situations, could be not too far out of the reach of already existing technology. In addition to the odd case of near-to-perfect alignment one might be lucky eneough to encounter in the Galaxy, there exist several astronomical sites where good alignment occurs naturally. A good example is when the electromagnetic source and the gravity-wave source are, respectively, a high-frequency pulsar and a neutron star, locked together in a tight binary. We are led to believe that neutron-star gravity waves might be directly observable in timing data of systems such as PSR B1913+16.
