Dark stars could help solve three pressing puzzles of the high-redshift universe
Phys.org••general
Key Points:
- A new study published in Universe explores how dark stars, powered by dark matter annihilations, could explain three major cosmic dawn puzzles revealed by the James Webb Space Telescope (JWST): "blue monster" galaxies, early overmassive black hole galaxies, and "little red dots" (LRDs).
- Dark stars, forming in dark matter-rich environments shortly after the Big Bang, can grow supermassive and serve as natural seeds for supermassive black holes, potentially resolving the unexpected brightness and compactness of blue monster galaxies and the presence of overmassive black holes at early cosmic times.
- JWST observations challenge pre-existing models of early galaxy and black hole formation by revealing ultra-compact, dustless galaxies and sources like LRD
