Journal Article
Shanks, T., Hogarth, L., & Metcalfe, N. (2019). Gaia Cepheid parallaxes and ‘Local Hole’ relieve H0 tension. Monthly Notices of the Royal Astronomical Society: Letters, 484(1), L64-L68. https://doi.org/10.1093/mnrasl/sly239

There is an ≈9 ± 2.5 per cent tension between the value of Hubble’s Constant, H0 = 67.4 ± 0.5 km s−1 Mpc−1, implied by the Planck microwave background power spectrum and that given by the distance scale of H0 = 73.4 ± 1.7 km s−1Mpc−1. But with a plau... Read More about Gaia Cepheid parallaxes and ‘Local Hole’ relieve H0 tension.
