The WiggleZ Dark Energy Survey: mapping the distance-redshift relation with baryon acoustic oscillations
Chris Blake,Eyal A. Kazin,Florian Beutler,Tamara M. Davis,Tamara M. Davis,David Parkinson,Sarah Brough,Matthew Colless,Carlos Contreras,Warrick J. Couch,Scott M. Croom,Darren J. Croton,Michael J. Drinkwater,Karl Forster,David Gilbank,Michael D. Gladders,Karl Glazebrook,Ben Jelliffe,Russell J. Jurek,I-hui Li,Barry F. Madore,D. Christopher Martin,Kevin A. Pimbblet,Gregory B. Poole,Michael Pracy,Michael Pracy,Rob Sharp,Rob Sharp,Emily Wisnioski,David Woods,Ted K. Wyder,Howard K. C. Yee +31 more
TL;DR: In this paper, the authors present measurements of the baryon acoustic peak at redshifts z = 0.44, 0.6 and 0.73 in the galaxy correlation function of the final dataset of the WiggleZ Dark Energy Survey.

TL;DR: In this paper, the authors performed a joint determination of the distance-redshift relation and cosmic expansion rate at redshifts z = 0.44, 0.6 and 0.73 by combining measurements of the baryon acoustic peak and Alcock-Paczynski distortion from galaxy clustering in the WiggleZ Dark Energy Survey, using a large ensemble of mock catalogues to calculate the covariance between the measurements.

TL;DR: In this article, the power spectrum of the velocity divergence field, P_(θθ) (k), was extracted from the WiggleZ Dark Energy Survey and compared with several different models of the quasi-linear growth of structure including empirical models, fitting formulae calibrated to N-body simulations and perturbation theory techniques.
