Evidence for Evolution or Bias in Host Extinctions of Type 1a Supernovae at High Redshift

Type la supernova magnitudes conventionally include an additive parameter called the extinction coefficient. We find that the extinction coefficients of a popular "gold" set are well correlated with the deviation of magnitudes from Hubble diagrams. If the effect is due to bias, extinctions...
