Supermassive Dark Stars and their remnants as a possible solution to three recent cosmic dawn puzzles

TL;DR

This paper proposes that Supermassive Dark Stars formed from dark matter annihilation could explain recent JWST observations of early galaxies and quasars, addressing key cosmic dawn puzzles.

Contribution

It introduces the concept that Supermassive Dark Stars can naturally resolve multiple challenges posed by recent JWST data.

Findings

Supermassive Dark Stars can reach masses of up to 10^6 solar masses.

SMDSs can produce the ultra-compact, bright high-z galaxies observed by JWST.

SMDSs may serve as progenitors of supermassive black holes in the early universe.

Abstract

The James Webb Space Telescope (JWST) has begun to revolutionize our view of the Cosmos. The discovery of Blue Monsters (i.e., ultra-compact yet very bright high-z galaxies) and the Little Red Dots (i.e., very compact dustless strong Balmer break cosmic dawn sources) pose significant challenges to pre-JWST era models of the assembly of first stars and galaxies. In addition, JWST data further strengthen the problem posed by the origin of the supermassive black holes that power the most distant quasars observed. Stars powered by Dark Matter annihilation (i.e., Dark Stars) can form out of primordial gas clouds during the cosmic dawn era and subsequently might grow via accretion and become supermassive. In this paper we argue that Supermassive Dark Stars (SMDSs) offer natural solutions to the three puzzles mentioned above.
