Literally nothing in the article positing that dark stars may indicate Supersymmetry, ugh! Dark stars are thought to be the annihilation of neutralinos. The gravity of these particles would be enough to draw hydrogen gas close together but the specific annihilation would generate heat preventing the hydrogen gas from coalescing to start nuclear fusion.
This is one of the purposed methods by which one would might observe a dark star. Some random cloud of hydrogen gas giving off way more heat in the form of gamma rays, neutrinos, and antimatter than a random cloud of hydrogen gas would be able to give off.
This is JADES-GS-z13-0, JADES-GS-z12-0, and JADES-GS-z11-0 which the light from has traveled 13.6 billion light-years, meaning that we're looking at a very early universe here. Which that makes sense, dark stars would have only been able to form in the earliest days of the universe. Back then, the density of neutralinos would have been high enough to encourage dark star production, the proper distance of JADES-GS-z13-0 et al is 33.6 billion light years, so yeah MUCH HIGHER concentration. However, with the continued expansion of the universe, the density would have dropped low enough to prevent high enough neutralino concentration to produce dark stars.
However, there is probably a non-supersymmetry way to explain dark stars that match up with the purposed candidates here. I just don't know it. The point being is that IF these are confirmed, there's a new strong argument for spuersymmetry, though I won't hold my breath. I know quite a few folk were disappointed with the lack of squarks in ATLAS at the LHC.
