Overview
- The object, dubbed ID830, is observed from about 12 billion years ago with an estimated mass of roughly 440 million Suns.
- Multiwavelength measurements, including ultraviolet and X-ray data, indicate an accretion rate around 13 times the classical Eddington limit.
- ID830 shows a bright X-ray–emitting corona alongside strong radio jets, a pairing many models do not expect during such extreme accretion.
- The team proposes a transient trigger such as shredding a massive giant star or engulfing a large gas cloud, with the super-Eddington phase lasting on the order of centuries.
- The peer-reviewed results, led by researchers at Waseda and Tohoku Universities and published Jan. 21 in The Astrophysical Journal, point to follow-up observations and searches for similar quasars.
