The April-June 2020 super-outburst of OJ 287 and its long-term multiwavelength light curve with Swift: binary supermassive black hole and jet activity
S. Komossa, D. Grupe, M. L. Parker +4
We report detection of a very bright X-ray-UV-optical outburst of OJ 287 in April-June 2020; the second brightest since the beginning of our Swift multi-year monitoring in late 201…
Spitzer Observations of the Predicted Eddington Flare from Blazar OJ 287
Seppo Laine, Lankeswar Dey, Mauri Valtonen +25
Binary black hole (BH) central engine description for the unique blazar OJ 287 predicted that the next secondary BH impact-induced bremsstrahlung flare should peak on 2019 July 31.…
Accretion Disk Parameters determined from the great 2015 flare of OJ 287
Mauri J. Valtonen, Staszek Zola, Pauli Pihajoki +17
In the binary black hole model of OJ 287 the secondary black hole orbits a much more massive primary, and impacts on the primary accretion disk at predictable times. We update the…
The Unique Blazar OJ 287 and its Massive Binary Black Hole Central Engine
Lankeswar Dey, Achamveedu Gopakumar, Mauri Valtonen +12
The bright blazar OJ 287 is the best-known candidate for hosting a nanohertz gravitational wave (GW) emitting supermassive binary black hole (SMBBH) in the present observable unive…
