For more than 150 years, the OJ 287 galaxy and its brightness variations five billion light years away has both puzzled and fascinated astronomers, because they suspect two supermassive black holes are merging in the core.
Look into the heart: Astronomers have gained detailed insights into the active galaxy OJ 287 for the first time – a galaxy that has long given way to riddles, because its brightness fluctuates over the cycle of around 60 years. Now, images of coupled orbital and terrestrial radio telescopes reveal unusual structures in the jet of this galaxy: it has multiple nods and has trillions of degrees of hot hotspots. What's behind it? The active galaxy O…
Observations reveal a plasma structure associated with the nucleus of the OJ 287 galaxy, 5 billion light years away.
For more than 150 years, the OJ 287 galaxy and its five billion light-year variations in brightness have been intrigued and fascinated, as they suspect that two supermassive black holes merge into the heart. An international research team led by Dr. Efthalia Traianou of the University of Heidelberg recently succeeded in [...]
