Measuring H0 from the 6dF Galaxy Survey and future low-redshift surveys
Published online by Cambridge University Press: 26 February 2013
Abstract
Baryon acoustic oscillations (BAO) at low redshift provide a precise and largely model-independent way to measure the Hubble constant, H0. The 6dF Galaxy Survey measurement of the BAO scale gives a value of H0 = 67 ± 3.2 km s−1 Mpc−1, achieving a 1σ precision of 5%. With improved analysis techniques, the planned wallaby (Hi) and taipan (optical) redshift surveys are predicted to measure H0 to 1–3% precision.
