Abstract

Abstract We report observations from the Hubble Space Telescope (HST) of Cepheid variables in the host galaxies of 42 Type Ia supernovae (SNe Ia) used to calibrate the Hubble constant ( H 0 ). These include the complete sample of all suitable SNe Ia discovered in the last four decades at redshift z ...
