Toward SED Reconstruction of Type Ia Supernovae with Rubin Observatory Simulations

We developed an inference pipeline for Type Ia supernova light curves using realistic Rubin Observatory simulations within the Cosmographi framework. The project forward-simulates sparse, noisy, multi-band photometry; infers SALT2 parameters—stretch, colour, peak time, and redshift—using grid search and machine-learning methods; and uses Bayesian MCMC to constrain shared corrections to the underlying spectral energy distribution. This provides an initial step toward learning supernova spectral models directly from photometry and propagating calibrated uncertainty into future classification and cosmological analyses.
