Effects of Type Ia Supernovae Absolute Magnitude Priors on the Hubble Constant Value

Effects of Type Ia Supernovae Absolute Magnitude Priors on the Hubble Constant Value

We systematically explore the influence of the prior of the peak absolute magnitude ( M ) of Type Ia supernovae (SNe Ia) on the measurement of the Hubble constant ( H _0 ) from SNe Ia observations. We consider five different data-motivated M priors, representing varying levels of dispersion, and ass...
