The host galaxy of OJ 287 revealed by optical and near-infrared imaging
K. Nilsson, J. Kotilainen, M. Valtonen +11
The BL Lacertae object OJ 287 (z = 0.306) has unique double-peaked optical outbursts every ~12 years, and it presents one of the best cases for a small-separation binary supermassi…
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.…
