Dark Matter the power behind the First Stars.
Prof. Douglas Spolyar (Stockholm)

The first stars form deep inside million solar mass halos within 100 million years of the big bang. As the gas cools and contracts, the dark matter becomes incredibly dense. If dark matter is a WIMP (one of the most promising dark matter candidates), the annihilation rate becomes sufficiently large to halt the collapse of the gas and to power a newly born star dubbed a Dark Star. We discuss the formation and evolution of Dark Stars and observational signatures for JWST
