Beyond Extreme Burstiness: Evolving Star Formation Efficiency as the Key to Early Galaxy Abundance
JWST observations have revealed an overabundance of bright galaxies at z ≥ 9, creating apparent tensions with theoretical predictions within standard ΛCDM cosmology. We address this challenge using a semiempirical approach that connects dark matter halos to the observed UV luminosity through a physi...
