Quantifying the CMB Degeneracy Between the Matter Density and Hubble Constant in Current Experiments

Joshua A. Kable, Graeme E. Addison, Charles L. Bennett

We revisit the degeneracy between the Hubble constant, $H_0$, and matter density, ${\Omega }_m$, for current cosmic microwave background (CMB) observations within the standard $\Lambda CDM$ model…
