Oral Presentation

Weak lensing science with CFHTLenS

Author(s): Van Waerbeke, and the CFHTLenS team

Presenter: Ludovic Van waerbeke (University of British Columbia)

Over the past three years, an international team of astronomers(CFHTLenS) has worked on the optimal analysis of the weak lensing signal using the CFHTLS-WIDE data. The data reduction chain was reshaped from scratch in order to meet the weak lensing requirements and make the residual systematics as low as possible. The results of this work will lead to approximately two dozen of publications in the coming year and half on various subjects from galaxy-galaxy lensing to clusters and large scale structure lensing. As coordinator of this effort, and on the behalf of the CFHTLenS team, I will present the preliminary results and highlight what have been the major breakthroughs in the reduction of systematics.
