NASA’s planet hunter satellite observes smaller object in a black hole pair directly for the first time

12.06.2024

Several international research groups have already confirmed the theory that there are two black holes at the centre of the distant galaxy OJ 287, first suggested by astronomers at the University of Turku, Finland. A new study shows that satellite observations conducted in 2021 revealed the smaller black hole of the pair for the first time.

New doctoral research sheds new light on how quasars are formed

Quasars are extremely luminous galaxies and their light is produced by a supermassive black hole at their center, which is actively feeding on the cosmic gas and dust around it. Previous theories have suggested that quasars and their supermassive black holes are formed when galaxies collide, but a recent doctoral thesis at the University of Turku shows that quasars can form even in the absence of galaxy interactions.
