我院天体物理光学AGN团组在天文学期刊《ApJ》上发表了题为“Effects of intrinsic AGN variability on optical QPOs related to sub-pc binary black hole systems in broad line AGN”的SCI文章。
在该项工作中,基于BBH动力学的时序转化,考虑每个黑洞吸积系统所对应的AGN内禀光变,明确了AGN内禀光变对真实观测数据中的QPOs信号的影响,为现在正在进行的光学QPOs周期在不同时期的变化提供了理论和模型基础。

Fig. 1: Top panels show the artificial light curves created by dynamical model related to BBH systems. Middle panels show the results determined by the GLS periodogram. Bottom panels show the results determined by the WWZ technique. In each middle panel, vertical lines in blue and in red show the positions for the determined periodicity and the intrinsic periodicity.
