A quasar from just 760 million years after the Big Bang challenges theory about formation of supermassive black holes in the early universe.
The rapid formation of supermassive black hole s in the early universe continues to perplex astronomers, and new observations from the James Webb Space Telescope have only added to the mystery; even challenging existing models of cosmic evolution.
These SMBHs form luminous accretion disks around them as they pull in gas and even entire star systems. The intense radiation from these disks can drive material out of the host galaxy in massive ‘relativistic’ jets, a phenomenon that can be observed in later cosmic periods. The discovery of such a quasar in the early universe suggests that SMBHs were not only present very soon after the Big Bang, but also well-integrated into their host galaxies soon after their formation.
Critically, the dust torus surrounding J1120+0641 is similar to those found in later quasars, which challenges one major theory about the early formation of SMBHs. Essentially, the JWST observations refute the idea that early SMBHs achieved their massive sizes through an “ultra-effective feeding mode;” essentially that there was some special mechanism in the early universe that allowed these black holes to accrete far more mass into it than the radiation from its accretion disk pushed away.
