Two black holes at quasar OJ287 (IMAGE)
Caption
Two black holes in orbit around each other in quasar OJ287. On the left is a theoretical diagram, calculated by Lankeswar Dey, showing where the black holes and the jets emanating from them were at the time when the picture was taken. On the right is part of an image taken by the system including the RadioAstron satellite (J.L. Gomez and et al., 2022), where the two lower bright spots are the radio emission coming from the two black holes, and the topmost spot is the jet of the smaller black hole. This is shown as a dashed line on the left-hand side diagram, while the black holes are shown as dots.
