The Optical Variation of the Blazar Object PKS 2155-304
摘要
Abstract
This paper uses the Swift satellite UVOT telescope observation data to obtain the light curve of PKS 2155-304 on optical U band and B band from November 17,2005 to September 8,2017.Jurkevich method is applied to the light curve,the analysis results show that the PKS 2155-304 on optical U band could have 237 days of quasi periodicity,B band could have 242 days of quasi periodicity.The results are validated by DCF method.The DCF method also found that optical U band and B band were strongly correlated without significant time delay.关键词
