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 Â± 3.2 km sâˆ’1 Mpcâˆ’1, achieving a 1Ïƒ precision of 5%. With improved analysis techniques, the planned wallaby (Hi) and taipan (optical) redshift surveys are predicted to measure H0 to 13% precision.
