[158.02] Very-low Frequency Gravitational Wave Detection with Pulsar Timing

F. A. Jenet (U. Texas at Brownsville)

Radio pulsars offer a unique opportunity to probe the nano-hertz regime of the gravitational wave (G-wave) spectrum. Such low frequency G-waves will provide a wealth of information about galaxy and supermassive black hole binary formation and evolution. The most likely signal detected using pulsar timing will be a stochastic G-wave background generated from an ensemble of supermassive black holes scattered throughout the universe. Techniques are currently being developed to detect such a background. Aside from the background, radio pulsars can place limits on the existence of individual G-wave sources. Using currently available data, limits have been placed on the mass of a recently proposed supermassive black hole system in the radio galaxy 3C 66B.
