Recently G. M. Fuller and X. Shi proposed that the gravitational collapse of supermassive objects (M 104 M☉) could be a cosmological source of γ-ray bursts (GRBs). The major advantage of their model is that supermassive object collapses are far more energetic than solar mass-scale compact mergers. Also, in their proposal the seeds of supermassive black holes (SMBHs) thus formed could give rise to the SMBHs observed at the center of many galaxies. We argue here that, besides the generation of GRBs, there could well occur a strong generation of gravitational waves (GWs) during the formation of SMBHs. As a result, the rate of such GW bursts could be as high as the rate of GRBs in the model by G. M. Fuller and X. Shi. In this case, the detection of GRBs and bursts of GWs should occur with a small time difference. We also argue that the GWs produced by the SMBHs studied here could be detected when the Laser Interferometric Space Antenna becomes operative.

Shi提出超质量物体（M 104M☉）的重力坍塌可能是γ射线爆发（GRB）的宇宙学来源。他们模型的主要优点是，超大质量物体的坍塌要比太阳系大规模紧凑型合并的能量要大得多。同样，在他们的建议中，如此形成的超大质量黑洞（SMBH）的种子可能会引起在许多星系中心观测到的SMBH。在这里，我们认为，除了GRB的产生以外，在SMBH的形成过程中很可能会大量产生引力波（GWs）。结果，这种GW爆发的速率可能与G. M. Fuller和X. Shi提出的模型中的GRB速率一样高。在这种情况下，GRB和GW突发的检测应该以很小的时间差进行。我们还认为，当激光干涉式空间天线开始工作时，可以检测到此处研究的SMBH产生的GW。
