Abstract
We study the relation of Type Ia Supernovae (SNe Ia) with host galaxies from a large low redshift sample. By examining the Hubble residuals of the entire sample from the best-fit cosmology, we show that SNe Ia in passive hosts are brighter than those in star-forming hosts after light curve correction at 2.1σconfidence level. We find that SNe Ia in high luminosity hosts are brighter after light-curve correction at>3σconfidence level. We also find that SNe Ia in large size galaxies are brighter after light-curve correction at?2σ confidence level. We demonstrate that the residual linearly depends on host luminosity at a confidence of 4σor host size at a confidence of 3.3σ.
