Almost Readily Detectable Time Delays from Gravity Waves?

Abstract

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