Strong Progenitor Age-bias in Supernova Cosmology. II. Alignment with DESI BAO and Signs of a Non-Accelerating Universe

Junhyuk Son, Young-Wook Lee, Chul Chung +2

Supernova (SN) cosmology is based on the key assumption that the luminosity standardization process of Type Ia SNe remains invariant with progenitor age. However, direct and extens…

Testing the effect of progenitor's metallicity on $^{56}$ Ni mass and constraining the progenitor scenarios in Type Ia supernovae

Young-Lo Kim, Chul Chung, Yong -Cheol Kim

The analytical model found that the intrinsic variation in the initial metallicity of the Type Ia supernova (SN Ia) progenitor stars ( $Z_{p r o g e ni t or}$ ) translates into a 25% variat…
