Measuring the 2D Baryon Acoustic Oscillation signal of galaxies in
  WiggleZ: Cosmological constraints
  We present results from the 2D anisotropic Baryon Acoustic Oscillation (BAO)
signal present in the final dataset from the WiggleZ Dark Energy Survey. We
analyse the WiggleZ data in two ways: firstly using the full shape of the 2D
correlation function and secondly focussing only on the position of the BAO
peak in the reconstructed data set. When fitting for the full shape of the 2D
correlation function we use a multipole expansion to compare with theory. When
we use the reconstructed data we marginalise over the shape and just measure
the position of the BAO peak, analysing the data in wedges separating the
signal along the line of sight from that parallel to the line of sight. We
verify our method with mock data and find the results to be free of bias or
systematic offsets. We also redo the pre-reconstruction angle averaged (1D)
WiggleZ BAO analysis with an improved covariance and present an updated result.
The final results are presented in the form of $\Omega_c h^2$, $H(z)$, and
$D_A(z)$ for three redshift bins with effective redshifts $z = 0.44$, $0.60$,
and $0.73$. Within these bins and methodologies, we recover constraints between
5% and 22% error. Our cosmological constraints are consistent with Flat
$\Lambda$CDM cosmology and agree with results from the Baryon Oscillation
Spectroscopic Survey (BOSS).
