JADES-GS-z13-0, JADES-GS-z12-0, and JADES-GS-z11-0

An article published in the journal “Proceedings of the National Academy of Sciences” reports the discovery of candidate supermassive dark stars observed by the James Webb Space Telescope. Cosmin Ilie, Jillian Paulin, and Katherine Freese argue that three of what were considered primordial galaxies have characteristics of a type of object that so far was only hypothesized. According to the model proposed in 2007, supermassive dark stars have a large dark matter component that powers them instead of nuclear fusion. These strange objects could reach masses up to ten million times the Sun’s and a brightness up to ten billion times the Sun’s, which could lead to mistaking them for primordial galaxies.
