CFHTLenS tomographic weak lensing: Quantifying accurate redshift distributions
Jonathan Benjamin, Ludovic Van Waerbeke, Catherine Heymans +18
The Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS) comprises deep multi-colour (u*g'r'i'z') photometry spanning 154 square degrees, with accurate photometric redshifts an…
CFHTLenS: Testing the Laws of Gravity with Tomographic Weak Lensing and Redshift Space Distortions
Fergus Simpson, Catherine Heymans, David Parkinson +20
Dark energy may be the first sign of new fundamental physics in the Universe, taking either a physical form or revealing a correction to Einsteinian gravity. Weak gravitational len…
On the shear estimation bias induced by the spatial variation of colour across galaxy profiles
Elisabetta Semboloni, Henk Hoekstra, Zhuoyi Huang +13
The spatial variation of the colour of a galaxy may introduce a bias in the measurement of its shape if the PSF profile depends on wavelength. We study how this bias depends on the…
Bayesian Galaxy Shape Measurement for Weak Lensing Surveys - III. Application to the Canada-France-Hawaii Telescope Lensing Survey
L. Miller, C. Heymans, T. D. Kitching +17
A likelihood-based method for measuring weak gravitational lensing shear in deep galaxy surveys is described and applied to the Canada-France-Hawaii Telescope (CFHT) Lensing Survey…
