| 摘要 | We have analyzed the radio light curves of the Seyfert galaxy III Zw 2 at 2:? 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. Period of P(obs) = 5.14 +/- 0.19 yr was consistently identified by three methods: the Jurkevich method, the power spectrum intensity estimation method and the discrete correlation function method. The variability period of about 5.14 yr in III Zw 2 is caused most likely by the helical motion of the jet. (C) 2009 Elsevier B.V. All rights reserved. |
