Very weak lensing in the CFHTLS Wide: Cosmology from cosmic shear in the linear regime
L. Fu, E. Semboloni, H. Hoekstra +16
We present an exploration of weak lensing by large-scale structure in the linear regime, using the third-year (T0003) CFHTLS Wide data release. Our results place tight constraints…
Testing Gravity with the CFHTLS-Wide Cosmic Shear Survey and SDSS LRGs
O. Doré, M. Martig, Y. Mellier +7
General relativity as one the pillar of modern cosmology has to be thoroughly tested if we want to achieve an accurate cosmology. We present the results from such a test on cosmolo…
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…
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…
CARS: the CFHTLS-Archive-Research Survey; I. Five-band multi-colour data from 37 sq. deg. CFHTLS-Wide observations
T. Erben, H. Hildebrandt, M. Lerchster +10
We present the CFHTLS-Archive-Research Survey (CARS). It is a virtual multi-colour survey based on public archive images from the CFHT-Legacy-Survey. Our main scientific interests…
