JWST/MIRI Reveals the True Number Density of Massive Galaxies in the Early Universe

Early JWST studies reporting an unexpected abundance of massive galaxies at z  ∼ 5–8 challenge galaxy formation models in the ΛCDM framework. Previous stellar mass ( M _⋆ ) estimates suffered from large uncertainties due to the lack of rest-frame near-infrared data. Using deep JWST/NIRCam and Mid-In...
