蝎虎座BL天体S5 0716+714光快变数据中的均方根-通量关系

Rms-flux relation in the optical fast variability data of BL Lacertae object S5 0716+714

Gabriela-Raluca Mocanu, Bulcsu Sandor

摘要:

分析了BL Lac S5 0716+714日内变异性(IDV)与通量的均方根(rms)呈线性关系的可能性。这一结果可作为目前关于活动星系核中光学IDV来源的争论的一个论据。使用了63个不同波段的时间序列。在低于8%的情况下,在高于65%的置信水平下恢复了均方根通量的线性关系。我们能够检查八个时间序列的震级是否为对数正态分布,并发现,置信度> 95%,情况并非如此。

英文摘要:

The possibility that BL Lac S5 0716+714 exhibits a linear root mean square (rms)-flux relation in its IntraDay Variability (IDV) is analysed. The results may be used as an argument in the existing debate regarding the source of optical IDV in Active Galactic Nuclei. 63 time series in different optical bands were used. A linear rms-flux relation at a confidence level higher than 65% was recovered for less than 8% of the cases. We were able to check if the magnitude is log-normally distributed for eight timeseries and found, with a confidence > 95%, that this is not the case.
