Researchers have developed a new Bayesian hierarchical model to analyze type Ia supernovae and their host galaxy photometry. This model aims to infer intrinsic supernova properties, their rate over time, and cosmological parameters from photometric data alone. By incorporating physics-based simulations for star formation and dust extinction, the approach can achieve precise photometric redshifts and significantly improve cosmological constraints compared to methods relying on limited spectroscopic data.
