Evidence for strong progenitor age dependence of type Ia supernova luminosity standardization process

Supernova (SN) cosmology is based on the assumption that width-luminosity relation (WLR) and color-luminosity (CLR) in type Ia SN luminosity standardization would not show {absolute magnitude differences} with progenitor age. Unlike this expectation, recent age datings of stellar populations host galaxies have shown significant correlations between Hubble residual (HR). Here we correlation originates from a strong dependence zero-points WLR CLR, sense SNe younger progenitors are fainter each at given light-curve parameters $x_1$ $c$. This $4.6\sigma$ result reminiscent Baade's discovery zero-point variation Cepheid period-luminosity age, and, as such, causes serious systematic bias redshift cosmology. Other properties substantially smaller insignificant offsets CLR for same dataset. We illustrate differences high-$z$ low-$z$ HR after standardization, fully comparable to those correspondingly young old intermediate redshift, indicating observed dimming may well be an artifact over-correction standardization. When properly taken into account, there little evidence left accelerating universe, discordance other probes, urging follow-up investigations larger samples different bins.
