论文摘要
我们提供了长期的光学$ r $带光曲线分析重力镜头Blazar AO 0235+164在1982年至2019年的时间跨度。分析的几种方法导致这些数据中存在〜8.13年的周期性。此外，这五个主要耀斑中的每一个显然都是双峰，主要峰值之后的次级峰值约2年。与众所周知的系统OJ 287一起，我们的发现构成了有史以来发现的大黄花中最安全的长期准周期光学行为的案例之一。二进制超级黑洞系统似乎为这些结果提供了很好的解释。
We present a long term optical $R$ band light curve analysis of the gravitationally lensed blazar AO 0235+164 in the time span 1982 - 2019. Several methods of analysis lead to the result that there is a periodicity of ~8.13 years present in these data. In addition, each of these five major flares are apparently double-peaked, with the secondary peak following the primary one by ~2 years. Along with the well known system, OJ 287, our finding constitutes one of the most secure cases of long term quasi-periodic optical behaviour in a blazar ever found. A binary supermassive black hole system appears to provide a good explanation for these results.
