Key Points

This research aims to investigate the relationship between supermassive dark stars and the formation of early black-hole seeds in the universe.
Analyzed JWST data of compact red sources and luminous galaxies at z ≳ 10
Explored the formation of black-hole seeds from supermassive dark stars powered by dark matter
Predicted associated spectral signatures for testing with JWST observations
Identified a population of compact red sources and luminous galaxies in early universe observations
Proposed that supermassive dark stars can form black-hole seeds between 10^5 to 10^7 solar masses
Predicted distinctive spectral signatures that can be tested with current JWST data

Abstract

AbstractJWST has unveiled a range of compact, red, line-broadened sources (“little red dots”) along-side a population of unexpectedly luminous galaxies at z ≳ 10. These observations revivequestions about the formation of early massive black-hole seeds and the rapid assembly of met-als and dust. We explore whether supermassive dark stars (SMDSs)—baryonic objects poweredtemporarily by dark-matter annihilation—offer a unified pathway to form ∼ 105 – 107M⊙ black-hole seeds very early on. This scenario predicts distinctive spectral signatures that can be testedwith current and forthcoming JWST data.
