On the Root Cause of the Host “Mass Step” in the Hubble Residuals of Type Ia Supernovae
It is well established that the Hubble residuals of Type Ia supernovae (SNe Ia) show the luminosity step with respect to their host galaxy stellar masses. This “mass step” is taken as an additional correction factor for the SN Ia luminosity standardization. Here we investigate the root cause of the...
