Reconciliation of the Surface Brightness Fluctuation and Type Ia Supernova Distance Scales
Reconciliation of the Surface Brightness Fluctuation and Type Ia Supernova Distance Scales
We present Hubble Space Telescope measurements of surface brightness fluctuation (SBF) distances to early-type galaxies that have hosted Type Ia supernovae (SNe Ia). The agreement in the relative SBF and SN Ia multicolor light-curve shape and delta-m15 distances is excellent. There is no systematic scale error with distance, and previous …
