Redshift dependence of type Ia supernova standardization parameters and implications for cosmological inference

Context. Type Ia supernovae (SNe Ia) are fundamental probes of cosmic expansion, whose luminosities are empirically standardized using correlations with light-curve stretch and color. A common assumption in cosmological analyses is that the standardization coefficients are independent of redshift. A...
