Abstract:OJ 287 is one of the most studied BL Lac objects with very long optical measurements whose spectrum has been well measured through radio to X-ray band. The most outstanding characteristic of OJ 287 is its 12-year period, which is discovered in the optical range and has also been confirmed in the X-ray band. OJ 287 is supposed to be a binary black hole system in which a secondary black hole passes the accretion disk of the primary black hole and produces two impact flashes per period. It has also been proposed … Show more
