Improving measurements of H(z) and DA (z) by analysing clustering anisotropies
The baryonic acoustic feature in galaxy clustering is a promising tool for constraining the nature of the cosmic acceleration, through measurements of expansion rates H and angular diameter distances DA. Angle-averaged measurements of clustering yield constraints on the quantity . However, to break the degeneracy between these two parameters one …
