论文摘要
我们正在执行OJ 287的最稠密，最长的多年多波长监测项目。 MOMO项目（OJ 287的多波长观测和建模）涵盖了从无线电到高能状态的波长。一些选定的观察结果与事件地平线望远镜（EHT）的观察结果同时进行。 MOMO旨在了解磁盘喷气物理学并测试OJ 287二进制黑洞情景的预测。在这里，我们在上下文中对极端爆发和最小态的讨论进行了讨论，然后重点介绍了2021年至2022年5月的最新磁通和光谱演变，包括持续不断的明亮无线电射击。此外，我们表明，没有证据表明我们的光学 - UV-X射线光曲线中的前体耀斑活性与任何次级超质量黑洞（SMBH）磁盘撞击有关，预计该磁盘的影响于12月23日的2021年开始。
We are carrying out the densest and longest multiyear, multiwavelength monitoring project of OJ 287 ever done. The project MOMO (Multiwavelength Observations and Modelling of OJ 287) covers wavelengths from the radio to the high-energy regime. A few selected observations are simultaneous with those of the Event Horizon Telescope (EHT). MOMO aims at understanding disk-jet physics and at testing predictions of the binary black hole scenario of OJ 287. Here, we present a discussion of extreme outburst and minima states in context, and then focus on the recent flux and spectral evolution between 2021 and May 2022, including an ongoing bright radio flare. Further, we show that there is no evidence for precursor flare activity in our optical-UV-X-ray light curves that would be associated with any secondary supermassive black hole (SMBH) disk impact and that was predicted to start as thermal flare on 2021 December 23.
