Bayesian Galaxy Shape Measurement for Weak Lensing Surveys -II. Application to Simulations

T. D. Kitching, L. Miller, C. E. Heymans +2

We extend the Bayesian model fitting shape measurement method presented in Miller et al. (2007) and use the method to estimate the shear from the Shear TEsting Programme simulation…

Systematic effects on dark energy from 3D weak shear

T. D. Kitching, A. N. Taylor, A. F. Heavens

We present an investigation into the potential effect of systematics inherent in multi-band wide field surveys on the dark energy equation of state determination for two 3D weak le…

Bayesian Galaxy Shape Measurement for Weak Lensing Surveys -I. Methodology and a Fast Fitting Algorithm

L. Miller, T. D. Kitching, C. Heymans +2

The principles of measuring the shapes of galaxies by a model-fitting approach are discussed in the context of shape-measurement for surveys of weak gravitational lensing. It is ar…

On model selection forecasting, Dark Energy and modified gravity

A. F. Heavens, T. D. Kitching, L. Verde

The Fisher matrix approach (Fisher 1935) allows one to calculate in advance how well a given experiment will be able to estimate model parameters, and has been an invaluable tool i…

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…
