A Spectroscopic Model of the Type Ia Supernova–Host-galaxy Mass Correlation from SALT3
The unknown cause of the correlation between Type Ia supernova (SN Ia) Hubble residuals and their host-galaxy masses (the “mass step”) may bias cosmological parameter measurements. To better understand the mass step, we develop a SALT3 light-curve model for SN cosmology that uses the host-galaxy mas...
