The effect of background galaxy contamination on the absolute magnitude and light curve speed class of type Ia supernovae
- Texas Univ., Austin (USA)
Observational data are presented in support of the hypothesis that background galaxy contamination is present in the photometric data of Ia supernovae and that this effect can account for the observed dispersion in the light curve speeds of most of Ia supernovae. The implication is that the observed dispersion in beta is artificial and that most of Ia supernovae have nearly homogeneous light curves. The result supports the notion that Ia supernovae are good standard candles. 26 refs.
