| 英文摘要 | We analyzed the radio light curves of 3C 454.3 at frequencies 22 and 37 GHz taken from the database of Metsahovi Radio Observatory, and found evidence of quasi-periodic activity. The light curves show great activity with very complicated non-sinusoidal variations. Two possible periods, a very weak one of 1.57 +/- 0.12 yr and a very strong one of 6.15 +/- 0.50 yr were consistently identified by two methods, the Jurkevich method and power spectrum estimation. The period of 6.15 +/- 0.50 yr is consistent with results previously reported by Ciaramella et al. and Webb et al. Applying the binary black hole model to the central structure we found black hole masses of 1.53 x 10(9) M-. and 1.86 x 10(8) M-., and predicted that the next radio outburst is to take place in 2006 March and April. |
