Bayesian analysis of type Ia supernova data
Wang, XF; Zhou, X; Li, ZW; Chen, L
AbstractRecently, the distances to type la supernova (SN Ia) at z similar to 0.5 have been measured with the motivation of estimating cosmological parameters. However, different sleuthing techniques tend to give inconsistent measurements for SN Ia distances (similar to0.3 mag), which significantly affects the determination of cosmological parameters. A Bayesian "hyper-parameter" procedure is used to analyse jointly the current SN Ia data, which considers the relative weights of different datasets. For a flat Universe, the combining analysis yields Omega(M) = 0.20 +/- 0.07.
