Supernova Time Dilation in Hybrid Expansion-Tired-Light Cosmologies

Rajendra P. Gupta, Nikolaos Samaras, Utkarsh Kumar

Dark Energy Survey has shown that the emission light curve widths $\Delta t_{\mathrm{em}}$ of supernovae increase to $\Delta t_{\mathrm{obs}}$, obeying $\Delta t_{\mathrm{obs}}/\Delta t_{\mathrm{em}}=(1+z{)}^b$ with $b=1.003\p…
