CFHTLenS: The Canada-France-Hawaii Telescope Lensing Survey - Imaging Data and Catalogue Products
T. Erben, H. Hildebrandt, L. Miller +29
We present data products from the Canada-France-Hawaii Telescope Lensing Survey (CFHTLenS). CFHTLenS is based on the Wide component of the Canada-France-Hawaii Telescope Legacy Sur…
CFHTLenS: Improving the quality of photometric redshifts with precision photometry
H. Hildebrandt, T. Erben, K. Kuijken +16
Here we present the results of various approaches to measure accurate colours and photometric redshifts (photo-z's) from wide-field imaging data. We use data from the Canada-France…
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…
CFHTLenS: Weak lensing calibrated scaling relations for low mass clusters of galaxies
K. Kettula, S. Giodini, E. van Uitert +24
We present weak lensing and X-ray analysis of 12 low mass clusters from the CFHTLenS and XMM-CFHTLS surveys. We combine these systems with high-mass systems from CCCP and low-mass…
3D Cosmic Shear: Cosmology from CFHTLenS
T. D. Kitching, A. F. Heavens, J. Alsing +19
This paper presents the first application of 3D cosmic shear to a wide-field weak lensing survey. 3D cosmic shear is a technique that analyses weak lensing in three dimensions usin…
The galaxy-halo connection from a joint lensing, clustering and abundance analysis in the CFHTLenS/VIPERS field
J. Coupon, S. Arnouts, L. van Waerbeke +31
We present new constraints on the relationship between galaxies and their host dark matter halos, measured from the location of the peak of the stellar-to-halo mass ratio (SHMR), u…
CFHTLenS: Higher-order galaxy-mass correlations probed by galaxy-galaxy-galaxy lensing
P. Simon, T. Erben, P. Schneider +16
We present the first direct measurement of the galaxy-matter bispectrum as a function of galaxy luminosity, stellar mass, and SED type. Our analysis uses a galaxy-galaxy-galaxy len…
