BL Lac S5 0716+714的X射线光变曲线中~ 30分钟的准周期振荡
A Quasi-Periodic Oscillation of ~ 30 Minutes in the X-ray Light Curve of the BL Lac S5 0716+714
摘要:
我们撤回了我们的主张,即BL Lacertae对象S5 0716 + 714的XMM-牛顿卫星光变曲线中的一个分量显示了$\sim$ 30分钟的准周期振荡(QPO)。虽然我们的原始周期图和小波分析给出了一致的结果,但一旦适当考虑低频红噪声用于周期图分析,则数据不会导致统计上显著的结果。
英文摘要:
We withdraw our claim that a component in an XMM-Newton satellite light curve of the BL Lacertae object S5 0716 + 714 shows quasi-periodic oscillations (QPOs) of $\sim$30 minutes. Although both our original periodogram and wavelet analyses gave consistent results, the data do not lead to a statistically significant result once red-noise at low frequencies is properly taken into account for periodogram analyses.
