英文摘要 | We study the relation between Type Ia Supernovae (SNe Ia) and properties of their host galaxies using a large sample with low redshift. 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 the 2.1σ confidence level. We find that SNe Ia in high luminosity hosts are brighter after light-curve correction at the > 3σ confidence level. We also find that SNe Ia in large galaxies are brighter after light-curve correction at the ≥2σ confidence level. We demonstrate that the residuals depend linearly on host luminosity at a confidence of 4σ or host size at a confidence of 3.3σ. |
