The Influence of Host Galaxies in Type Ia Supernova Cosmology

Uddin, S; Mould, Jeremy; Lidman, Christopher; Ruhlmann-Kleider, V; Zhang, Bonnie


We use a sample of 1338 spectroscopically confirmed and photometrically classified Type Ia supernovae (SNe Ia) sourced from Carnegie Supernova Project, Center for Astrophysics Supernova Survey, Sloan Digital Sky Survey-II, and SuperNova Legacy Survey SN samples to examine the relationships between SNe Ia and the galaxies that host them. Our results provide confirmation with improved statistical significance that SNe Ia, after standardization, are on average more luminous in massive hosts...[Show more]
