Riess et al. (SH0ES metallicity corrections) / standard Cepheid calibration literature
authors
reviewer:will-blair
Cepheid variable distance ladder calibration exhibits metallicity-dependent period-luminosity relations that shift inferred distances by 5-8% when not corrected, directly propagating to H0 uncertainty.
