We present precise measurements of the growth rate of cosmic structure for the redshift range 0.1 < z < 0.9, using redshift-space distortions in the galaxy power spectrum of the WiggleZ Dark Energy Survey. Our results, which have a precision of around 10 per cent in four independent redshift bins, are well fitted by a flat Λ cold dark matter (ΛCDM) cosmological model with matter density parameter Ω_m = 0.27. Our analysis hence indicates that this model provides a self-consistent description of… 

The WiggleZ Dark Energy Survey: measuring the cosmic growth rate with the two-point galaxy correlation function

The growth history of large-scale structure in the Universe is a powerful probe of the cosmological model, including the nature of dark energy. We study the growth rate of cosmic structure to

The WiggleZ Dark Energy Survey: constraining galaxy bias and cosmic growth with three-point correlation functions

Higher order statistics are a useful and complementary tool for measuring the clustering of galaxies, containing information on the non-Gaussian evolution and morphology of large-scale structure in

Using the topology of large-scale structure in the WiggleZ Dark Energy Survey as a cosmological standard ruler

We present new and accurate measurements of the cosmic distance-redshift relation, spanning 0.2 10 Mpc/h considered in this analysis. The measured amplitudes then determine the cosmic distance

The WiggleZ Galaxy Survey shows that dark energy is real

The WiggleZ Dark Energy Survey on the Anglo-Australian Telescope has measured redshifts for 220,000 emission line galaxies. The galaxies sample a volume of 1 cubic Gpc and a redshift range of 0.2 < z

The 6dF Galaxy Survey: cosmological constraints from the velocity power spectrum

We present scale-dependent measurements of the normalized growth rate of structure f sigma 8(k, z = 0) using only the peculiar motions of galaxies. We use data from the 6-degree Field Galaxy Survey

The WiggleZ Dark Energy Survey: joint measurements of the expansion and growth history at z < 1

We perform 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

A combined measurement of cosmic growth and expansion from clusters of galaxies, the CMB and galaxy clustering

Combining galaxy cluster data from the ROSAT All-Sky Survey and the Chandra Xray Observatory, cosmic microwave background data from the Wilkinson Microwave Anisotropy Probe, and galaxy clustering

The WiggleZ Dark Energy Survey: measuring the cosmic expansion history using the Alcock-Paczynski test and distant supernovae

Astronomical observations suggest that today’s Universe is dominated by a dark energy of unknown physical origin. One of the most notable results obtained from many models is that dark energy should


Peculiar velocities are an important probe of the growth rate of mass density fluctuations in the universe. Most previous studies have focused exclusively on measuring peculiar velocities at

We have made the largest volume measurement to date of the transition to large-scale homogeneity in the distribution of galaxies. We use the WiggleZ survey, a spectroscopic survey of over 200 000

A test of the nature of cosmic acceleration using galaxy redshift distortions

Using a new survey of more than 10,000 faint galaxies, the anisotropy parameter β = 0.70 ± 0.26 is measured, which is consistent with the standard cosmological-constant model with low matter density and flat geometry, although the error bars are still too large to distinguish among alternative origins for the accelerated expansion.
