UHZ1 and the other three most distant quasars observed: possible evidence for Supermassive Dark Stars

Understand

The James Webb Space Telescope (JWST) has recently uncovered a new record-breaking quasar, UHZ1, at a redshift of $z\sim10$.

• This discovery continues JWST's trend of confronting the expectations from the standard $\Lambda$CDM model of cosmology with challenges.
• Namely, too many very massive galaxies and quasars have been observed at very high redshifts, when the universe was only a few hundred million years old.
• We have previously shown that Supermassive Dark Stars (SMDSs) may offer a solution to this puzzle.
