Description

I will review the local measurement by the SHOES team of the current rate of expansion (H0) of the universe from HST observations of Cepheid variables in host galaxies of Type Ia Supernovae. This measurement is a significant improvement from past measurements, and reduces many systematic uncertainties in past analyses. I will discuss the tension of our measurements with the inferred value of H0 from CMB measurements. I will also go over what improvements to expect in the next two years.
