Elemental gas-phase abundances of intermediate redshift type Ia supernova star-forming host galaxies

M. E. Moreno-Raya, L. Galbany, A. R. López-Sánchez +4

The maximum luminosity of type Ia supernovae (SNe Ia) depends on the oxygen abundance of the regions of the host galaxies where they explode. This metallicity dependence reduces th…
