CFHTLenS: Mapping the Large Scale Structure with Gravitational Lensing
Ludovic Van Waerbeke, Jonathan Benjamin, Thomas Erben +18
We present a quantitative analysis of the largest contiguous maps of projected mass density obtained from gravitational lensing shear. We use data from the 154 deg2 covered by the…
CFHTLenS: Cosmological constraints from a combination of cosmic shear two-point and three-point correlations
Liping Fu, Martin Kilbinger, Thomas Erben +17
Higher-order, non-Gaussian aspects of the large-scale structure carry valuable information on structure formation and cosmology, which is complementary to second-order statistics.…
CFHTLenS: Co-evolution of galaxies and their dark matter haloes
Michael J. Hudson, Bryan R. Gillis, Jean Coupon +16
Galaxy-galaxy weak lensing is a direct probe of the mean matter distribution around galaxies. The depth and sky coverage of the CFHT Legacy Survey yield statistically significant g…
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…
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: A Weak Lensing Shear Analysis of the 3D-Matched-Filter Galaxy Clusters
Jes Ford, Ludovic Van Waerbeke, Martha Milkeraitis +17
We present the cluster mass-richness scaling relation calibrated by a weak lensing analysis of >18000 galaxy cluster candidates in the Canada-France-Hawaii Telescope Lensing Survey…
