Gravitational Lensing with CFHTLenS: Results and Lessons Learned
Presented by Ludo van Waerbeke -- Host: Alina Kiessling
University of British Columbia

Thursday, January 24, 2013
4:00 P.M. in 169-336

Abstract
The CFHTLenS team has been working full time for the past 3 and a half years on the analysis of the 154 sq.deg. of the Canada France Telescope Legacy Survey (CFHTLS). Our main goal was gravitational lensing science, and most of the practical work focused on measuring the galaxy shapes and photometric redshifts with the best possible precision. In my talk I will present some of the science results, most of them are either accepted or under review. I will highlight some of the lessons learned from this project that will be useful for future lensing surveys. Full access to all our data products through the Canadian Astronomy Data Center (CADC) has been available since November 1, 2012.
