OJ 287: Potential Rosetta stone for the nascent multi messenger nano Hz GW astronomy

Recent observational campaigns and theoretical investigations strongly indicate the presence of a spinning supermassive black hole binary that spirals in due to the emission of nano-Hertz gravitational waves in bright blazar OJ 287. I will briefly describe these efforts, while focusing on our August 2019 observations and its implications. Additionally, I will list our on-going efforts, relevant to i) the Event Horizon Telescope consortium and ii) the International Pulsar Timing Array consortium which aims to detect GWs from such massive BH systems in the near future. These efforts should be helpful to achieve multi-messenger nano-Hz GW astronomy in the near future.
