Scientists find ancient black hole breaking the cosmic 'speed limit,' challenging multiple theories
Yahoo • • science
Key Points:
- The quasar ID830, a supermassive black hole from 12 billion years ago, is breaking astrophysical norms by simultaneously exceeding the Eddington growth limit and emitting strong X-ray and radio waves, which are typically not observed together.
- ID830's mass was already 440 million times that of the Sun when the universe was only about 15% of its current age, making it over 100 times more massive than the Milky Way’s central black hole, Sagittarius A*.
- Researchers found that ID830 is accreting matter at roughly 13 times the Eddington limit, likely due to a sudden influx of gas or the disruption of a massive star or gas cloud, a super-Eddington phase expected
