Cosmological constraints from COMBO-17 using 3D weak lensing
T. D. Kitching, A. F. Heavens, A. N. Taylor +5
We present the first application of the 3D cosmic shear method developed in Heavens et al. (2006) and the geometric shear-ratio analysis developed in Taylor et al. (2006), to the C…
Measuring dark energy properties with 3D cosmic shear
A. F. Heavens, T. D. Kitching, A. N. Taylor
We present parameter estimation forecasts for present and future 3D cosmic shear surveys. We demonstrate that, in conjunction with results from cosmic microwave background (CMB) ex…
Probing dark energy with the shear-ratio geometric test
A. N. Taylor, T. D. Kitching, D. J. Bacon +1
We adapt the Jain--Taylor (2003) shear-ratio geometric lensing method to measure the dark energy equation of state, and its time derivative from dark matter haloes in cosmologies w…
