Direct Te-based metallicities at z≈10 are 3× lower than at z=0-3, extending the gradual FMR offset and pointing to pristine gas inflows during early galaxy assembly.
COLIBRE simulations match observed galaxy stellar mass functions, star formation rates, and quenched fractions from z=17 to z=0, including JWST massive quiescent galaxies at high redshift.
Upper limits on the cosmic abundance of Kardashev Type III radio-broadcasting populations are set at less than one per 10^17 stars using radio source counts and commensal SETI field limits.
