Gravitational wave detection using high precision pulsar timing observations

摘要：

It is possible that the first detection of gravitational waves (GWs) will be made by pulsar timing experiments. Precise observations of millisecond pulsars over a period of ~5yr will provide the sensitivity required to detect ultra-low frequency GWs if they are at the level predicted by current models. Such GWs may be detected as a single burst event or from slowly evolving individual supermassive black-hole binary systems. Additionally, models of galaxy mergers, the inflationary era and cosmic strings all predict the existence of a potentially detectable stochastic GW background. This paper reviews the current status of the Parkes Pulsar Timing Array project and describes the detectable gravitational wave sources.
