Can CMB Lensing Help Cosmic Shear Surveys? | | Sudeep Das

11 Nov 2013 | | Abstract: | Yes! Upcoming galaxy shear surveys have the potential to significantly
improve our understanding of dark energy and neutrino mass if lensing
systematics can be sufficiently controlled. The cross-correlations between the
weak lensing shear, galaxy number counts from a galaxy redshift survey, and the
CMB lensing convergence can be used to calibrate the shear multiplicative bias,
one of the most challenging systematics in lensing surveys. These
cross-correlations can significantly reduce the deleterious effects of the
uncertainties in multiplicative bias. | | Source: | arXiv, 1311.2338 | | Services: | Forum | Review | PDF | Favorites | |
