Cosmic Shear: Potential and Prospects
Sarah Bridle (University College London)

I discuss cosmological constraints from cosmic shear and focus on current work in the areas of shear measurement and intrinsic alignments. The GREAT08 Challenge will be launched this summer aiming the problem of extracting shear at communities outside of gravitational lensing, including the computer science community. I also overview the requirements on imaging, spectra and simulations needed to overcome potential contamination of cosmic shear by galaxy intrinsic alignments.
