Signatures of Rapidly Rotating Stars with Chemically Homogeneous Evolution in the First Galaxies
Published 2025-01-01“…We find that the rest-frame UV luminosity of star-forming galaxies can be significantly enhanced by a factor of ∼3−6 when CHE stars above a minimum initial mass of ${m}_{\star ,\min }^{\mathrm{CHE}}\sim 2-10\,{M}_{\odot }$ account for more than half of the total stellar mass following a Salpeter initial mass function. As a result, the UV luminosity functions observed at z ∼ 12−16 can be reproduced with less extreme values of star formation efficiency and UV luminosity stochastic variability. …”
