Cosmic Shear Tomography and Efficient Data Compression using COSEBIs

Understand

Context.

• Gravitational lensing is one of the leading tools in understanding the dark side of the Universe.
• The need for accurate, efficient and effective methods which are able to extract this information along with other cosmological parameters from cosmic shear data is ever growing.
• COSEBIs, Complete Orthogonal Sets of E-/B-Integrals, is a recently developed statistical measure that encompasses the complete E-/B-mode separable information contained in the shear correlation functions measured on a finite angular range.
