Abstract: The first observational evidence for the cosmic acceleration appeared from the type Ia supernovae (SNe Ia) Hubble diagram from two different groups. However, the empirical treatment of SNe Ia and their ability to show cosmic acceleration have been the subject of some debate in the literature. In this work we probe the assumption of redshift-independent absolute magnitude (M B ) of SNe along with its correlation with spatial curvature (Ω k0 ) and cosmic distance duality relation (CDDR) parameter (η(z)). This wo… Show more
