Gravitational-wave bursts from the nuclei of distant galaxies and quasars: proposal for detection using Doppler tracking of interplanetary spacecraft
It is likely that supermassive black holes (M approximately equal to 1,000,000 to 10 billion solar masses) exist in the nuclei of many quasars and galaxies. The collapse which forms these holes and subsequent collisions between them should produce strong, broadband bursts of gravitational waves: for a source of mass M at the Hubble distance of approximately 10 billion light years, the dimensionless amplitude would be approximately equal to 2x10/sup -17/ x (M/1,000,000 solar masses), and the duration of the burst would be T approximately equals (90 s)x(M/1,000,000 solar masses). Such bursts might arrive at earth as often as 50 times per year or as rarely as once in 300 years. The detection of such bursts may be possible within the next few years by using dual frequency Doppler tracking of interplanetary spacecraft. (auth)
