BayeSN and SALT: A Comparison of Dust Inference Across SN Ia Light-curve Models with DES5YR

Matthew Grayling, Brodie Popovic

In recent years there has been significant debate around the impact of dust on SNe Ia, a major source of uncertainty in cosmological analyses. We perform the first validation of th…

Bird-Snack: Bayesian Inference of dust law $R_{V}$ Distributions using SN Ia Apparent Colours at peaK

Sam M. Ward, Suhail Dhawan, Kaisey S. Mandel +2

To reduce systematic uncertainties in Type Ia supernova (SN Ia) cosmology, the host galaxy dust law shape parameter, $R_{V}$ , must be accurately constrained. We thus develop a comput…
