Type Ia supernovae (SNe Ia) are powerful tools for measuring the expansion history of the universe, but the impact of dust around SNe Ia remains unknown and is a critical systematic uncertainty. One way to improve our empirical description of dust is to analyse highly reddened SNe Ia (E (B βˆ’ V) > 0.4, roughly equivalent to the fitted SALT2 light-curve parameter c > 0.3). With the recently released Pantheon+ sample, there are 57 SNe Ia that were removed because of their high colour alone (with…
