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…

Origins of weak lensing systematics, and requirements on future instrumentation (or knowledge of instrumentation)

Richard Massey, Henk Hoekstra, Thomas Kitching +11

The first half of this paper explores the origin of systematic biases in the measurement of weak gravitational lensing. Compared to previous work, we expand the investigation of PS…
